THE  NORTH  AMERICAN  CEUTHOPHILI^ 
BY  SAMUEL  H.  SCUDDER. 

Presented  May  9,  1894 

THE  Ceuthophili  are  wingless  Locustarians  in  which  the  tarsi  are 
distinctly  compressed  rather  than  depressed,  with  no  pulvilli,*  the  hind 
tibiae  furnished  on  the  outer  margins  above  with  spines  of  two  distinct 
grades,f  the  fore  femora  without  foramina  or  genicular  spines,  the 
hind  femora  with  the  angle  of  their  insertion  on  the  inner  and  not  on 
the  outer  side  beneath,  and  the  antennae  strongly  approximated  at 
base.  They  are  all  apterous. 

With  the  exception  of  the  genus  Troglophilus  Krauss,  with  two 
species  from  European  caverns,  and  the  genus  Talitropis  Bol.,  with  a 
single  species  from  New  Zealand,  placed  respectively  at  one  and  the 
other  end  of  the  series,  they  are  known  only  from  America ;  and  with 
the  further  exception  of  Heteromallus  Brunner,  with  two  species 
from  Chili,  they  are  all  peculiar  to  the  United  States  and  Northern 
Mexico.  Here  they  include  six  genera  and  sixty-seven  species,  the 
genus  Ceuthophilus  alone  containing  above  fifty  species.  The  larger 
proportion  of  them,  if  not  all  (excepting  Udeopsylla  nigrd),  frequent 
dark  places,  such  as  burrows,  pits,  caverns,  wells,  hollow  trees,  and 
especially  the  crevices  beneath  fallen  logs. 

They  were  first  made  known  in  this  country  by  the  descriptions  of 
Haldeman,  Girard,  and  Harris,  and  before  their  time  only  a  single 
species  from  this  country  had  been  described,  by  Burmeister.  Not  a 
species  of  the  group,  even  the  European,  was  known  to  Serville.  My 
first  systematic  paper,  in  1861,  was  a  study  of  "  Rhaphidophora " 
(Proc.  Bost.  Soc.  Nat.  Hist.,  VIII.)  where  seven  of  our  species  were 

*  Brunner  states  that  Gammarotettix  has  a  single  pulvillus  on  the  first  tarsal 
joint;  but  although  the  treading  surface  of  this  joint  (as  of  the  succeeding)  is 
broad,  I  can  find  no  indication  of  a  true  pulvillus. 

t  This  feature  is  obscure  in  Gammarotettix,    where  there  are  alternating 
longer  and  shorter  spines  of  such  slight  inequality  as  easily  to  be  overlooked, 
and  which  in  the  Table  of  Genera  given  below  is  ignored.

described  or  catalogued ;  but  their  diversity  was  hardly  fully  recog- 
nized when  in  the  following  year  I  published  my  Materials  for  a 
Monograph  of  the  li'orth  American  Orthoptera  (Bost.  Journ.  Nat. 
Hist.,  VII.),  where  eighteen  species  and  five  genera  were  characterized 
or  indicated ;  since  then  a  few  more  species  have  been  described,  by 
Thomas,  Brunner,  Bruner,  Packard,  Walker,  Blatchley,  and  myself, 
until  now  the  number  of  nominal  species  is  twenty-eight,  which  must, 
however,  be  reduced  by  synonymy  and  by  reference  to  other  genera  to 
twenty. 

In  1888,  Brunner,  in  his  Monographie  der  Stenopelmatiden  und 
Gyllacriden  (Verb.  Zool.-bot.  Gesellsch.  Wien),  subjected  all  the  spe- 
cies known  to  him  to  systematic  treatment ;  but  as  the  larger  part  of 
our  species  and  some  of  our  genera  were  unknown  to  him,  and  the 
number  of  separately  described  species  has  multiplied  so  greatly  while 
still  not  including,  at  least  in  Ceuthophilus,  the  half  of  our  species,  it 
has  seemed  desirable  to  undertake  a  revision  of  the  group,  so  far  as 
our  native  species  are  concerned,  and  in  the  genus  Ceuthophilus  to 
redescribe  all  the  older  forms,  as  well  as  to  publish  the  novelties. 
Accordingly  in  the  present  paper  thirty-eight  additional  species  of 
the  group  are  characterized,  together  with  a  new  genus,  while  I  shall 
further  show  the  validity  of  Daihinia  of  Haldeman,  which  has  been 
called  in  question  by  Brunner,  and  shall  point  out  first  that  one  of  the 
genera  thought  to  belong  here  should  be  separated  as  a  member  of  a 
distinct  group.  The  total  number  of  genera  from  North  America  is 
therefore  six,  and  of  the  species  sixty-seven,  while  a  number  of  other 
species  are  known  to  me  imperfectly  by  a  single  sex  or  poor  examples. 

TROPIDISCHIA  SCUDDER. 

Tropidischia  Scudd.,  Bost.  Journ.  Nat.  Hist.,  vii.  440-441  (1862). 

in  his  Monograph  of  the  Stenopelmatidae,  Brunner  von  Wattenwyl, 
from  the  insufficient  data  given  in  my  two  statements  regarding  the 
structure  of  this  creature,  incorrectly  surmised  that  this  genus  should 
be  placed  in  the  Ceuthophili,  and  was  perhaps  congeneric  with  Hetero- 
mallus,  a  Chilian  genus.  Since,  however,  the  hind  tibiae  are  supplied 
above  with  spines  of  one  grade  only,  it  is  plainly  more  nearly  related 
to  the  Dolichopodae,  from  which  it  may  be  distinguished  by  the  simi- 
larly spined  margins  of  the  under  surface.  It  seems  to  form  a  group 
apart,  between  the  Dolichopodae  and  Ceuthophili,  and  of  equivalent 
value.  It  appears  to  come  nearer  Hadenoecus  and  Dolichopoda  than 
to  any  other  described  genera.

In  addition  to  the  characters  mentioned  above  and  those  given  in 
previous  descriptions,  I  may  add  that  all  the  legs  are  tetraquetrous, 
with  all  the  margins  spined,  the  spines  similar  in  character  and  uni- 
formly crowded,  excepting  on  the  lower  margins  of  the  fore  femora, 
the  inner  carina  of  which  is  sparsely  spiued,  the  outer  carina  unarmed; 
also  the  lower  margins  of  the  middle  femora,  both  carinae  of  which  are 
sparsely  spined  on  the  apical  half ;  and  the  hind  femora,  the  four 
carinae  of  which,  even  on  the  swollen  portion,  are  armed  excepting  at 
the  extreme  base,  though  both  the  inferior  carinae  are  rather  sparsely 
spined.  There  are  no  spines  on  the  genicular  lobes  of  the  femora, 
excepting  a  very  slight  one  on  the  posterior  side  of  the  middle  femora. 
There  are  but  two  pair  of  calcaria  on  the  hind  tibias,  the  upper  the 
longer  and  less  than  half  as  long  as  the  first  tarsal  joint.  The  hind 
tarsi  are  very  strongly  compressed,  carinate  beneath  without  pulvilli, 
about  two  fifths  as  long  as  the  hind  tibiae,  the  first  joint  nearly  as  long 
as  the  remaining  joints  together,  the  second  and  fourth  joints  of  the 
same  length  and  either  of  them  three  times  as  long  as  the  third. 
Finally,  the  subgenital  lamina  of  the  male  is  ample,  the  hind  margin 
entire,  with  minute  styles,  consisting  of  a  single  bluntly  conical  joint ; 
and  the  ovipositor  is  slender,  gently  arcuate,  tapering  and  acuminate, 
unarmed  at  tip.

Brunn.,  Monogr.  Stenop.,  61  (1888). 

This  is  one  of  the  dominant  American  genera  of  Locustariae,  con- 
fined to  North  America  and  almost  entirely  to  the  United  States, 
embracing  a  large  number  of  species  in  every  section  of  the  country, 
of  which  fifty-five  are  here  characterized.  Several  others  are  known 
to  me  by  single  specimens  or  mutilated  examples.  The  following 
table  is  based  principally  upon  the  males.  It  has  been  impossible  to 
construct  it  so  as  to  bring  together  the  allied  species,  whose  relation- 
ship is  better  shown  by  the  order  in  which  they  are  described,  though 
even  here  the  arrangement  is  far  from  satisfactory,  nearly  allied 
species  being  sometimes  separated  at  considerable  distances  in  order  to 
bring  them  in  closer  relation  with  other  allies.  Although  I  have  had 
six  hundred  and  fifty  examples  to  study  at  this  time,  besides  others  in 
alcohol,  the  material  is  still  insufficient  to  make  a  satisfactory  disposi- 
tion of  our  species,  and  I  am  confident  that  very  many  more  yet 
remain  to  be  discovered.

color  especially  interrupted  on  the  anterior  half  of  the  pronotum ;  this 
is  heavily  margined  by  subconfluent  dark  blotches  or  spots,  and  the 
dark  color  prevails  over  the  rest  of  the  thorax,  with  oblique  patches  of 
the  lighter  tints  on  the  meso-  and  metanotutn,  irregular  vermiculate 
blotches  of  greater  or  less  extent  on  the  pronotum  and  the  lower

Ground  color  of  body  varying  from  luteous  to  dark  castaneous,  very 
heavily  marked  with  blackish  fuscous,  so  that  the  latter  is  often  or 
perhaps  generally  the  prevailing  tint;  the  darker  colors  prevail  always 
on  the  hinder  half  of  all  the  segments  but  the  pronotum  and  some- 
times, especially  in  young  specimens,  to  such  an  extent  that  all  parts 
behind  the  pronotum  are  blackish  fuscous,  dotted  with  luteous ;  in  the 
lightest  colored  specimens,  the  dark  coloring  prevails  on  the  pronotum 
along  the  anterior  and  especially  the  posterior  margins,  and  is  generally 
present  in  a  subdorsal  posterior  tongue  emitted  on  either  side  from  the 
anterior  margin  ;  the  anterior  edge  of  the  dark  posterior  markings  of 
each  segment,  especially  in  the  front  portion  of  the  body,  is  exceed- 
ingly irregular  and  broken,  and  the  lightest  parts  are  more  or  less  and 
irregularly  clouded  with  fuscous ;  the  femora  are  usually  of  the  pre- 
vailing tint  of  the  body,  but,  even  when  the  body  is  dark,  are  some- 
times luteous  throughout  as  the  tibia?  and  tarsi  always  are,  except  for 
occasional  infuscation  of  the  former  at  base ;  the  outer  sides  of  the 
hind  femora  have  the  characteristic  markings  of  the  genus  more  or  less 
distinct.  Antennse  moderately  coarse  at  base,  tapering  with  great 
regularity,  3-4  times  the  length  of  the  body.  Legs  very  long  and 
slender.  Fore  femora  no  stouter  than  the  middle  femora,  more  than 
half  as  long  again  as  the  pronotum,  especially  in  the  £,  distinctly  less 
than  half  as  long  as  the  fore  femora,  the  inner  carina  usually  with  2-3

Middle  femora  with  3-4  spines  on  either  carina,  the  hind  carina 
with  a  not  very  long  genicular  spine.  Hind  femora  as  long  as  or 
longer  than  the  body,  considerably  more  than  twice  the  length  of  the 
fore  femora,  very  stout  at  base,  but  gradually  diminishing  in  stout- 
ness so  that  the  distal  third  is  slender  and  subequal  and  the  whole 
less  than  three  and  a  half  times  longer  than  broad,  the  surface  mostly 
glabrous,  but  on  the  darker  portions  above  beset  not  very  sparsely 
with  feeble  raised  points,  the  outer  carina  with  about  thirteen  distant  un- 
equal rather  coarse  spines,  the  longest  shorter  than  the  tibial  spurs  (  $ ) 
or  almost  unarmed  (9),  the  inner  carina  much  less  elevated  than 
the  outer,  with  equal  abortive  denticulations  numerous  in  the  £,  in- 
frequent and  equidistant  in  the  9 ,  the  intervening  sulcus  moderately 
broad.  Hind  tibiae  rather  slender,  straight  or  in  old  male  specimens 
gently  subarcuate  or  slightly  waved  in  the  proximal  third,  nearly  a 
sixth  longer  than  the  femora,  armed  beneath  usually  with  two  aligned 
preapical  spines  besides  the  apical  pair ;  spurs  subopposite,  the  basal 
pair  near  end  of  proximal  fourth  of  tibia,  less  than  half  as  long 
again  as  the  tibial  depth,  set  at  an  angle  of  about  40°  with  the  tibia 
and  usually  divaricating  about  60°,  but  sometimes  to  as  much  as 
twice  that,  incurved  especially  at  tip;  inner  middle  calcaria  much 
longer  than  the  outer,  more  than  twice  as  long  as  the  other  calcaria, 
about  twice  the  length  of  the  spurs,  but  much  shorter  than  the  first 
tarsal  joint.  Hind  tarsi  much  less  than  half  as  long  as  the  tibia,  the 
first  not  so  long  as  the  rest  together,  the  second  nearly  three  times  as 
long  as  the  third  and  with  tt  fully  as  long  as  the  fourth.  Cerci  stout  at 
base,  tapering  throughout,  nearly  a  third  as  long  as  the  hind  femora. 
Ovipositor  with  the  basal  third  rather  stout,  beyond  equal  and  rather 
slender,  nearly  three  fourths  the  length  of  the  hind  femora,  the  arma-

on  the  thoracic  segments,  though  nowhere  in  large  masses,  but,  except 
the  luteous  bordering  of  the  inferior  margins,  more  as  if  through  the 
confluence  of  minute  spots.  There  is  always  a  narrow  mediodorsal  line 
or  stripe  on  the  thoracic  segments  with  slight  expansions  anteriorly  and 
posteriorly  on  the  pronotum ;  legs  luteous  with  heavy  blackish  infusca-

long  as  the  tibial  spurs  (^)  or  with  2—3  feeble  serrations  (9),  the 
inner  carina  with  distant  feeble  minute  spinules  (9)?  the  intervening 
sulcus  slender.  Hind  tibiae  sinuate  in  the  proximal  half  (  <?)  or  straight 
throughout  (9),  considerably  longer  than  the  femora  (scarcely  longer 
in  Eastern  examples),  armed  beneath  with  a  single  subapical  spine 
besides  the  apical  pair ;  spurs  subopposite,  the  basal  just  before  the 
end  of  the  proximal  third  of  the  tibia,  about  half  as  long  again  as  the

6.     CEUTHOPHILUS  GRANDIS,  sp.  nov. 

Body  dark  luteo-castaneous  very  heavily  marked  with  blackish  or 
blackish  fuscous,  which  is  heaviest  at  the  posterior  margins  of  all  the 
segments,  along  the  front  margin  of  the  pronotum,  and  in  a  stripe 
bordering  the  broad  mediodorsal  rufo-luteous  stripe  of  the  pronotum  ; 
the  anterior  lower  angle  of  the  pronotum,  and  to  some  extent  that 
of  the  other  thoracic  segments,  are  dull  luteous,  merging  with  the 
luteous  of  the  central  portion  of  the  descending  lobes  ;  on  the  abdomen 
the  darker  colors  prevail  above  to  such  a  degree  that  the  luteous 
appears  to  be  maculate  on  a  dark  ground ;  antennas  and  legs  luteo- 
testaceous,  more  or  less  though  generally  feebly  infuscate,  the  hind 
femora  with  fuscous  scalariform  markings,  apically  broadly  marked 
with  fuscous  but  preceded  by  a  broad  more  or  less  clearly  marked 
luteous  annulation.  The  antennae  are  slender  except  near  the  base 
and  fully  four  times  as  long  as  the  body,  the  legs  very  long  and 
slender.  Fore  femora  scarcely  stouter  than  the  middle  femora,  barely 
half  as  long  as  the  hind  femora,  two  thirds  (<J)  or  three  fifths  (  9  )  as 
long  again  as  the  pronotum,  the  inner  carina  with  3-4  spines  none  of 
them  very  long  nor  very  unequal.  Middle  femora  similarly  armed 
on  the  front  carina  and  on  the  hind  carina  3-4  spines  besides  the 
moderately  long  genicular  spine.  Hind  femora  as  long  as  the  body, 
very  little  more  than  twice  as  long  as  the  fore  femora,  pretty  stout  at 
base,  but  with  the  slender  portion  much  produced,  the  apical  third  or 
in  the  female  even  more  than  that  being  subequal,  the  whole  being  in  the 
male  nearly  four  and  a  half  times  longer  than  broad,  the  surface  above 
and  on  both  sides  just  beyond  the  middle  with  a  few  scattered  raised 
points,  the  outer  carina  armed  throughout  all  but  extreme  base  with 
8-12  distant,  not  greatly  unequal,  subequidistant  spines,  the  longest 
scarcely  so  long  as  the  tibial  spurs  but  tumid  at  base  (  $ )  or  with 
similarly  distant  feeble  serrulations  (9),  the  inner  carina  sparsely  (£} 
or  very  sparsely  (  9  )  serrulate,  the  intervening  sulcus  narrow.  Hind

besides  the  apical  pair ;  spurs  subopposite,  the  basal  at  about  the  end 
of  the  proximal  third  of  the  tibia,  slightly  longer  than  the  tibial  depth, 
set  at  an  angle  of  50-60°  with  the  tibia  and  divaricating  about  120°, 
their  tips  much  incurved ;  inner  middle  calcaria  very  much  longer  than 
the  outer,  fully  twice  as  long  as  the  others  or  as  the  spurs  and  nearly 
as  long  as  the  first  joint  of  the  tarsi.  Hind  tarsi  two  fifths  as  long  as 
the  tibia?,  the  first  joint  about  as  long  as  the  rest  together,  the  second 
nearly  three  times  as  long  as  the  third  and  with  it  as  long  as  the 
fourth.  Cerci  slender  and  delicately  tapering,  a  quarter  as  long  again 
as  the  femoral  breadth.  Ovipositor  more  than  half  as  long  as  the  hind 
tibiae,  the  lower  margin  straight,  not  stout  and  gently  tapering  in  the 
basal  half,  slender  and  equal  in  the  apical  half,  the  tip  upturned  and 
bluntly  acuminate,  the  teeth  of  the  inner  valves  triangular  and  rather

This  species  is  not  far  removed  from  G.  gracilipes  in  structural 
details,  though  with  much  duller  and  less  diversified  markings. 

7.     CEUTHOPHLLUS  SECRETUS,  sp.  nov. 

In  markings  this  species  agrees  altogether  with  O.  palmeri  except 
that  the  luteous  colors  are  clearer  and  that  the  abdomen  is  more  com- 
pletely fuscous,  the  luteous  being  almost  entirely  confined  to  a  narrow 
stripe  across  the  anterior  margin,  not  seen  when  the  segments  are 
contracted.  The  antennae  are  fully  three  times  the  length  of  the 
body,  slender  and  gradually  tapering,  the  legs  long  and  slender. 
Fore  femora  scarcely  stouter  than  middle  femora,  considerably  more 
than  half  as  long  again  as  the  pronotum  and  about  half  as  long  as  the 
hind  femora,  the  inner  carina  with  1-3  small  spines.  Middle  femora 
with  2-4  spines  of  varying  length  on  the  front  carina,  and  on  the  hind 
carina  occasionally  a  single  small  spine  besides  the  long  genicular  spine. 
Hind  femora  nearly  as  long  as  the  body,  about  twice  the  length  of  the 
fore  femora,  tapering  with  no  abruptness,  nearly  four  times  as  long  as 
broad,  the  apical  fourth  subequal,  with  scattered  but  nowhere  numerous 
minute  raised  points  on  the  upper  apical  half,  the  outer  carina  with

Glabrous,  mottled  with  luteous  and  blackish  fuscous,  both  colors 
varying  in  tint  in  different  individuals  ;  there  is  often,  but  not  always,  a 
mediodorsal  light  stripe  on  the  thorax  bordered  by  dark  tints,  and  the 
lower  portions  of  the  sides  are  always  lighter  than  the  rest ;  the  inter- 
vening portions  of  the  thorax  may  be  described  as  fuscous,  heavily 
sprinkled  and  blotched  irregularly  with  luteous,  sometimes  one,  some- 
times the  other  prevailing ;  on  the  abdomen  the  darker  colors  prevail 
and  the  lighter  appear  as  a  tolerably  regular  and  profuse  sprinkling  of 
often  confluent  luteous  dots,  most  abundant  on  the  posterior  portions 
of  the  segments ;  the  hind  femora  have  the  usual  markings,  and  are 
feebly  and  narrowly  infuscate  apically.  The  antennae  are  slender,

fully  twice  as  long  as  the  body,  the  legs  moderately  short.  Fore  femora 
not  stouter  than  the  middle  pair,  a  third  longer  than  the  pronotum  and 
distinctly  less  than  half  as  long  as  the  hind  femora,  the  inner  carina 
with  a  long  preapical  spine  sometimes  accompanied  by  a  shorter  one. 
Middle  femora  with  1-2  spines  on  the  front  carina  besides  a  preapical 
spine,  and  on  the  hind  carina  usually  two  spines  besides  the  genicular 
spine.  Hind  femora  somewhat  shorter  than  the  body,  considerably 
more  than  twice  as  long  as  the  fore  femora,  less  than  three  times  as 
long  as  broad,  the  swollen  portion  pretty  stout,  hardly  more  than  the 
distal  sixth  of  equal  width,  with  a  few  feebly  raised  points  on  the 
upper  apical  portion  of  the  inner  side  only,  the  outer  carina  delicately 
uniformly  and  densely  serrate  throughout  (<?)  or  with  a  few  apical 
obscure  serrations  (9)>  the  inner  carina  similar.  Hind  tibiae  straight 
in  both  sexes,  rather  stout  in  the  male,  scarcely  exceeding  the  femora 
in  length,  armed  beneath  with  a  preapical  spine  besides  the  apical  pair ; 
spurs  subopposite,  the  basal  beyond  the  end  of  the  proximal  third  of 
the  tibia,  hardly  or  no  longer  than  the  tibial  depth,  set  at  an  angle

inner  middle  calcaria  somewhat  longer  than  the  outer,  twice  as  long  as 
the  others  or  as  the  spurs,  but  not  so  long  as  the  first  tarsal  joint. 
Hind  tarsi  two  fifths  the  length  of  the  tibiae,  the  first  joint  nearly  as 
long  as  the  rest  together,  the  second  twice  as  long  as  the  third  and  with 
it  longer  than  the  fourth.  Cerci  rather  slender  throughout,  tapering, 
pointed,  as  long  as  the  femoral  breadth.  Ovipositor  less  than  three 
fifths  as  long  as  the  hind  femora,  gently  tapering  in  the  proximal  half, 
equal  and  not  very  slender  in  the  distal  half,  the  tip  upturned  a  little

14.    CETJTHOPHILUS  CELATUS,  sp.  nov. 

Body  blackish  fuscous,  glabrous,  liberally  sprinkled  with  luteo- 
testaceous  giving  it  a  speckled  appearance  in  best  marked  specimens ; 
some  of  these  spots  or  dots  are  clustered  in  a  more  or  less  conspicuous 
mediodorsal  stripe,  while  others  margin  subequidistantly  the  posterior 
border  of  all  the  abdominal  segments  or  are  submarginal ;  on  the  pro- 
notuna  and  to  a  less  degree  on  the  meso-  and  metanotum  they  are  liable 
to  coalesce  and  form  vague  and  irregular  patches  and  blotches ;  the 
fore  and  middle  legs  are  luteous,  more  or  less  infuscated  especially  at 
the  distal  ends  of  the  femora ;  hind  femora  brownish  fuscous,  often 
with  an  olivaceous  tint,  the  scalariform  markings  nearly  obsolete. 
Antennae  very  slender,  about  twice  the  length  of  the  body,  the  legs 
rather  short.  Fore  femora  no  stouter  than  the  middle  femora,  about 
a  third  (  (?)  or  a  fourth  (9  )  longer  than  the  pronotum,  and  much  less 
than  half  as  long  as  the  hind  femora,  the  inner  carina  with  a  subapical 
spine  sometimes  accompanied  by  a  few  others  near  it.  Middle  femora 
with  a  subapical  spine  sometimes  accompanied  by  one  or  two  others 
on  the  front  carina,  and  on  the  hind  carina  a  not  very  long  genicular 
spine  sometimes  accompanied  by  two  others.  Hind  femora  rather 
slender,  tapering  almost  regularly,  about  three  and  a  half  times  as  long 
as  broad,  considerably  more  than  twice  as  long  as  the  fore  femora, 
with  no  raised  points  upon  the  surface,  the  outer  carina  very  finely 
denticulate  (  $ )  or  wholly  or  almost  wholly  unarmed  ( 9 )  >  the  inner 
carina  feebly  and  very  finely  serratulate,  the  intervening  sulcus  narrow. 
Hind  tibiae  straight  in  both  sexes,  a  little  longer  than  the  femora, 
slender,  armed  beneath  with  a  single  subapical  spine  besides  the  apical 
pair ;  spurs  opposite  or  subopposite,  the  basal  at  the  end  of  the  proxi- 
mal fourth  of  the  tibia,  no  longer  than  the  tibial  depth,  set  at  an  angle 
of  about  45°  with  the  tibia  and  divaricating  about  60° ;  inner  middle 
calcaria  considerably  longer  than  the  outer,  more  than  twice  as  long 
as  the  others  or  as  the  spurs,  but  shorter  than  the  first  tarsal  joint. 
Hind  tarsi  a  little  less  than  half  as  long  as  the  tibia,  the  first  joint 
scarcely  as  long  as  the  rest  together,  the  second  much  more  than 
twice  as  long  as  the  third  and  with  it  longer  than  the  fourth.  Cerci 
slight,  tapering  regularly,  about  three  fourths  as  long  as  the  femoral 
breadth.  Ovipositor  straight,  tapering  on  the  proximal,  slender  and 
equal  on  the  distal  half,  somewhat  more  than  half  as  long  as  the  hind 
femora,  the  tip  very  gradually  attenuated  and  very  slightly  upcurved, 
not  very  finely  pointed,  the  inner  valves  rather  feebly  crenulate.

Dull  fuliginous  brown,  but  glabrous,  marked  with  very  dull  and  pale 
luteous  dots,  occasionally  somewhat  confluent ;  there  is  sometimes,  but 
rarely,  a  mediodorsal  luteous  stripe  on  the  pronotum ;  the  dots  are 
generally  a  little  elongate  and  margin  the  segments  posteriorly,  often 
turned  obliquely  inward  and  when  accompanied  by  other  dots  in 
advance  these  arranged  to  give  an  added  obliquity  to  their  general 
course  ;  the  pronotura  is  more  or  less  marmorate  with  dull  luteous  ; 
the  legs  have  the  general  tone  of  the  body  and  the  hind  femora  the 
usual  markings  of  the  genus,  the  darker  colors  generally  the  more 
extensive,  but  the  pattern  obscured  apically  so  that  the  distal  extremity 
of  the  femora,  including  more  than  the  geniculation,  is  more  or  less 
deeply  infuscated.  The  antennas  are  stout  at  base  but  immediately 
become  slender  and  are  at  least  twice  as  long  as  the  body.  The  legs 
are  short  and  rather  slender.  Fore  femora  no  stouter  than  the  middle 
femora,  a  third  longer  than  the  pronotum  and  about  half  as  long  as 
the  hind  femora,  the  inner  carina  with  a  subapical  spine.  Middle 
femora  with  a  subapical  spine  on  the  front  carina  and  on  the  hind 
carina  1-2  spines,  sometimes  wanting  in  the  9 ,  besides  a  fairly  long 
genicular  spine.  Hind  femora  moderately  stout  and  plump,  regularly 
tapering,  about  three  and  a  half  times  longer  than  broad,  the  distal 
fifth  equal,  the  surface  with  no  raised  points,  both  carinas  sparsely  and 
finely  serrate  in  the  £,  almost  unarmed  in  the  9>  the  intervening 
sulcus  of  moderate  breadth  and  V-snaPed-  Hind  tibia?  considerably 
longer  than  the  femora,  unusually  slender,  straight  in  both  sexes, 
armed  beneath  with  two  preapical  spines  besides  the  apical  pair ; 
spurs  subopposite,  the  basal  at  the  end  of  the  proximal  fourth  of  the 
tibia,  nearly  half  as  long  again  as  the  tibial  depth,  set  at  an  angle  of 
40-45°  with  the  tibia  and  divaricating  about  135°,  their  tips  incurved; 
inner  middle  calcaria  considerably  longer  than  the  outer,  nearly  twice

tarsal  joint.  Hind  tarsi  about  two  fifths  the  length  of  the  tibia,  the 
first  joint  shorter  than  the  others  together,  the  second  twice  as  long 
as  the  third  and  with  it  as  long  as  the  fourth.  Cerci  rather  slender, 
regularly  tapering,  slightly  longer  than  the  femoral  breadth.  Oviposi- 
tor gently  tapering  on  proximal,  equal  on  distal  half,  rather  slender, 
very  slightly  arcuate,  two  thirds  the  length  of  the  hind  femora,  the

with  his  description,  the  species  formerly  referred  by  me  and  others 
to  this  being  a  Northern  form  to  which  the  description  poorly  fits, 
and  that  described  by  Brunner  under  this  name  is  a  very  different

17.     CEDTHOPHILUS  ARIZONENSIS,  sp.  nov. 

Pallid  luteous,  so  heavily  infuscated  that  behind  the  pronotum  there 
is  only  left  a  single  series  of  luteous  spots  on  each  side,  which  on  the 
meso-  and  metanotum  are  transverse  oval  and  rather  large,  and  on 
the  abdomen  are  transverse  anterior  stripes,  sometimes  confluent  with 
those  of  the  opposite  side ;  the  pronotum  is  mostly  fuscous,  deepest 
around  the  margin,  more  or  less  dotted  and  vermiculate  with  luteous 
elsewhere,  there  being  commonly  a  transverse  row  of  dots  bordering 
the  anterior  fuscous  margin,  and  the  disk  on  either  side  more  or  less 
heavily  blotched  with  the  same ;  the  legs  are  fuscous,  varying  in  depth 
in  different  individuals,  the  hind  femora  generally  with  sufficiently 
conspicuous  scalariform  markings.  The  antennae  are  very  slender  and 
fully  three  times  as  long  as  the  body,  and  the  legs  are  slender  but  not 
very  long.  Fore  femora  slightly  stouter  than  the  middle  femora,  a 
third  longer  than  the  pronotum  and  half  as  long  as  the  hind  femora, 
the  inner  carina  with  one  or  two  spines.  Middle  femora  with  1-3 
spines  on  the  front  carina,  and  the  hind  carina  generally  unarmed 
except  for  a  slight  genicular  spine,  but  sometimes  with  as  many  as 
three  other  minute  spines.  Hind  femora  nearly  as  long  as  the  body, 
twice  the  length  of  the  fore  femora,  moderately  slender,  being  a  little 
less  than  three  and  a  half  times  longer  than  broad,  gradually  diminish- 
ing in  size  and  yet  with  the  distal  fourth  subequal,  the  surface  with  no 
raised  points,  the  outer  carina  with  only  a  few  raised  points,  mostly  on 
the  distal  half,  the  inner  carina  with  most  minute  but  sharp  distant 
spinules,  the  intervening  sulcus  narrow.  Hind  tibia?  scarcely  longer 
than  the  femora,  straight  in  both  sexes,  very  slender,  armed  beneath 
with  a  single  preapical  spine  besides  the  apical  pair;  spurs  nearly 
opposite,  the  basal  beyond  the  end  of  the  proximal  third  of  the  tibia, 
about  as  long  as  the  tibial  depth,  set  at  an  angle  of  from  35-40°  with 
the  tibia  and  generally  divaricating  about  70-80°  (one  example  about 
100°),  their  tips  incurved  ;  inner  middle  calcaria  a  little  longer  than 
the  outer,  fully  twice  as  long  as  the  others  or  as  the  spurs,  but  much 
shorter  than  the  first  tarsal  joint.  Hind  tarsi  less  than  half  as  long 
as  the  tibiae,  the  first  joint  fully  as  long  as  the  rest  combined,  the 
second  twice  as  long  as  the  third  and  with  it  as  long  as  the  fourth. 
Cerci  stout  on  the  proximal,  slender  on  the  distal  half,  nearly  as  long 
as  the  femoral  breadth.  Ovipositor  four  fifths  the  length  of  the  hind 
femora,  slender,  nearly  straight,  tapering  slightly,  the  tip  finely  pointed 
at  an  angle  of  about  30°  and  barely  upturned,  the  armature  of  the 
inner  valves  aculeate,  only  the  terminal  arcuate.

Smoky  luteo-testaceous  with  a  slight  olivaceous  tinge,  glabrous, 
marked  more  or  less  deeply  with  fuscous  along  the  posterior  margins  of 
the  segments  and  generally  along  the  anterior  margin  of  the  pronotum  ; 
in  this  posterior  infuscation  are  indistinct  dots  of  luteous  in  a  trans- 
verse series ;  generally  there  is  also  a  mediodorsal  luteous  line  over 
all  the  segments  but  deepest  and  broadest  on  the  pronotum,  which  is 
also  laterally  irregularly  streaked,  clouded,  or  blotched  with  luteous  ; 
beyond  the  lighter  more  luteous  bases  of  the  femora,  the  legs  are  of 
the  body  color,  but  the  hind  femora  are  considerably  inf'uscated  in  a 
scalariform  pattern,  apically  confluent.  The  antennae  are  slender  and 
nearly  or  quite  three  times  the  length  of  the  body  and  the  legs  are 
moderately  short.  Fore  femora  no  stouter  than  the  middle  femora, 
more  than  a  third  ($}  or  less  than  a  fourth  (9)  longer  than  the 
pronotum  and  somewhat  less  than  half  as  long  as  the  hind  femora, 
the  inner  carina  armed  only  with  a  subapical  spine.  Middle  femora 
with  two  spines  on  the  front  carina,  and  on  the  hind  carina  2-3  (9) 
or  3-4  (c£)  spines  besides  a  not  very  long  genicular  spine.  Hind 
femora  nearly  as  long  as  ($}  or  much  shorter  than  (9)  the  body, 
a  little  more  than  twice  as  long  as  the  fore  femora  especially  in  the  9 , 
pretty  stout,  in  the  $  being  but  a  little  more  than  two  and  a  half  times 
longer  than  broad,  though  in  the  9  fully  three  and  a  quarter  times  as 
long  as  broad,  with  no  raised  points  on  the  surface,  or  at  most  four  or 
five  scattered  insignificant  ones  on  the  inner  surface  in  the  £,  the 
outer  carina  with  a  few  spinous  points  on  the  distal  half,  the  inner 
carina  similarly  armed  but  in  the  £  weaker,  the  intervening  sulcus 
narrow.  Hind  tibiae  scarcely  or  no  longer  than  the  femora,  straight

besides  the  apical  pair ;  spurs  almost  opposite,  the  basal  rather  beyond 
the  end  of  the  proximal  third  of  the  tibia,  scarcely  longer  (<J)  or  a  little 
longer  (?)  than  the  tibial  depth,  set  at  an  angle  of  about  45°  with  the 
tibia  and  divaricating  70-90°,  their  tips  incurved;  inner  middle 
calcaria  distinctly  longer  than  the  outer,  twice  as  long  as  the  others 
or  as  the  spurs,  but  distinctly  shorter  than  the  first  tarsal  joint. 
Hind  tarsi  nearly  half  as  long  as  the  tibiae,  the  first  joint  fully  (J1)  or 
nearly  (9)  as  long  as  the  rest  taken  together,  the  second  more  than 
twice  as  loug  as  the  third  and  nearly  as  long  as  the  fourth.  Cerci 
rather  stout  tapering  from  before  the  middle,  shorter  than  the  femoral 
breadth.  Ovipositor  nearly  twice  as  long  as  the  fore  femora  and  not 
very  much  shorter  than  the  hind  tibiae,  beyond  the  extreme  very 
slightly  swollen  base  slender  and  subequal  but  gently  tapering,  slightly 
arcuate  in  the  distal  half,  the  extreme  tip  produced  to  a  very  fine 
scarcely  upturned  point,  the  armature  including  the  apical  members 
consisting  of  sharp  minute  reversed  serrations  hardly  apparent  until 
mature.

19.  CEDTHOPHILUS  HEROS,  sp.  nov. 

Body  castaneous,  so  heavily  marked  with  black  or  blackish  fuscous 
as  to  appear  rather  as  black  marked  with  castaneous ;  the  latter 
appears  on  the  pronotum  only  in  a  very  broad  mediodorsal  stripe  of 
unequal  width,  an  impure  blotch  in  the  middle  of  the  sides  usually 
connected  with  the  former,  and  an  inferior  edging  sometimes  expand- 
ing anteriorly  ;  in  younger  specimens,  however,  it  extends  over  nearly 
all  the  surface  ;  on  the  meso-  and  metanotum  it  margins  the  segments 
anteriorly  except  below,  separated  from  the  black  irregularly,  and 
extends  mediodorsally  across  the  segments  ;  on  the  abdomen  it  appears 
as  small  spots  dotting  the  surface  and  merging  along  the  anterior  mar- 
gins ;  the  antennae  are  pale  fuscous  obscurely  and  distantly  annulated 
with  luteous;  the  legs  are  castaneous,  more  or  less  infuscated,  the

hind  femora  externally  marked  heavily  with  fuscous  in  a  scalariform 
pattern,  with  a  broad  obscure  castaneous  annulation  well  before  the 
genicular  lobes.  The  antennae  are  slender  and  exceedingly  long, 
about  four  times  as  long  as  the  body,  and  the  legs  are  very  long  though 
only  moderately  slender.  Fore  femora  no  stouter  than  the  middle 
femora,  a  little  less  than  half  as  long  as  the  hind  femora,  and  rather 
more  (<£)  or  rather  less  (9)  than  three  fourths  as  long  again  as  the 
pronotum,  the  inner  carina  with  2-3  spines.  Middle  femora  with 
similar  spines  on  the  front  carina  and  on  the  hind  carina  a  couple  of 
similar  spines  besides  a  not  very  long  genicular  spine.  Hind  femora 
fully  as  long  as  the  body,  a  little  more  than  twice  as  long  as  the  fore 
femora,  the  basal  portion  stout  and  swollen  but  delicately  tapering  so 
that  nearly  or  in  the  female  quite  the  apical  third  is  subequal,  and  the 
whole  is  four  times  as  long  as  broad,  the  upper  edge  of  the  inner  sur- 
face with  4-5  distant  raised  points,  the  outer  carina  with  about  ten 
sub-equal  spines,  the  longest  much  shorter  than  the  tibial  spurs  ((?), 
or  with  about  six  slight  and  distant  recumbent  spines  (9)>  the  inner 
carina  rather  bluntly  denticulate,  distantly  in  the  outer  half  ((J)  or 
like  the  outer  carina  but  more  closely  denticulate  (9)»  the  intervening 
sulcus  narrow.  Hind  tibiae  barely  arcuate  at  base  (<J)  or  straight  (9), 
a  very  little  longer  than  the  femora,  armed  beneath  with  1-2  sub- 
apical  spines  besides  the  apical  pair ;  spurs  subopposite,  the  basal  at 
the  end  of  the  proximal  third  of  the  tibia,  a  little  longer  than  the  tibial 
depth,  set  at  an  angle  of  about  60°  with  the  tibia  and  divaricating 
about  130°  (<J)  or  150-170°  (9),  incurved  at  tip;  inner  middle  cal- 
caria  a  little  longer  than  the  outer,  twice  as  long  as  the  others  or  as 
the  spurs,  and  as  long  as  the  first  tarsal  joint.  Hind  tarsi  two  fifths 
as  long  as  the  tibia?,  the  first  joint  much  shorter  than  the  rest  together, 
the  second  nearly  three  times  as  long  as  the  third  and  with  it  fully  as 
long  as  the  fourth.  Cerci  slender,  nearly  half  as  long  again  as  the 
femoral  breadth.  Ovipositor  three  fifths  as  long  as  the  hind  femora, 
straight,  tapering  and  not  very  stout  in  the  basal,  slender  and  equal  in 
the  apical  half,  the  apex  obliquely  truncate,  upturned,  and  acuminate 
but  not  much  produced,  the  teeth  of  the  inner  valves  rather  short 
and  aculeate.

Dull  luteo-  or  rufo-testaceous,  very  heavily  flecked  with  dark  fuscous 
so  as  to  produce  a  tolerably  uniform  mottled  appearance,  ordinarily  a 
little  more  open  than  elsewhere  in  a  narrow  mediodorsal  streak  on  the 
pronotum,  and  in  the  tolerably  clear  luteous  or  pallid  luteous  of  the 
inferior  margin  of  the  descending  thoracic  lobes ;  the  flecking  is  made 
up  of  small  more  or  less  confluent  dots,  which  assume  a  certain  longi- 
tudinal regularity  on  the  abdomen  only ;  legs  varying  from  luteous  to 
testaceous,  more  or  less  infuscated,  especially  on  the  apical  portions  of 
the  femora  and  in  the  distinct  and  heavy  scalariform  markings  of  the 
hind  femora.  The  antennae  are  moderately  stout  in  the  basal,  but  in 
the  apical  half  very  slender,  apparently  only  a  little  more  than  twice  the 
length  of  the  body,  the  legs  moderately  long.  Fore  femora  no  stouter

the  front  carina  as  in  the  fore  femora,  the  hind  carina  armed  with  1—3 
spines  besides  a  moderately  long  genicular  spine.  Hind  femora 
longer  (<J)  or  shorter  (9)  than  the  body,  considerably  more  than  twice 
as  long  as  the  fore  femora  (at  least  a  third  more  in  the  male),  stout,  the

angle  of  about  35°  with  the  tibia  and  divaricating  80°-90°,  the  apical 
half  incurved ;  inner  middle  calcaria  much  longer  than  the  outer,  more 
than  twice  as  long  as  the  others  or  as  the  spurs,  but  scarcely  so  long 
as  the  first  tarsal  joint.  Hind  tarsi  two  fifths  as  long  as  the  tibias,  the 
first  joint  about  as  long  as  the  rest  together,  the  second  nearly  three 
times  as  long  as  the  third  and  with  it  fully  as  long  as  the  fourth.

(1894). 

In  color  and  markings  this  species  is  indistinguishable  from  0.  uhleri. 
The  legs  and  especially  the  hind  femora  are  slenderer.  Fore  femora 
no  stouter  than  the  hind  femora,  much  less  than  half  as  long  as  the 
fore  femora,  fully  a  third  (£)  or  scarcely  a  fourth  (9)  as  long  again 
as  the  pronotum,  the  inner  carina  with  2-3  spines,  the  subapical  long. 
Middle  femora  armed  on  the  front  carina  much  as  in  the  fore  legs,  the 
hind  carina  with  a  long  genicular  spine  sometimes  accompanied  by  1-3 
other  spines,  often  minute.  Hind  femora  nearly  two  and  a  half  times 
as  long  as  the  fore  femora,  longer  than  the  body  in  both  sexes,  slender 
and  tapering,  nearly  the  apical  third  subequal,  three  and  a  half  times

as  long  as  broad  in  the  male  and  fully  three  and  three  quarters  in  the 
female,  the  upper  portion  of  the  apical  half  of  the  inner  surface  and 
to  a  less  degree  the  upper  surface  near  it  with  numerous  raised  points, 
but  not  so  pronounced  as  in  C.  uhleri,  the  outer  carina  armed  exactly 
as  there  but  with  wider  intervals  between  the  larger  spines  and  the 
spines  less  stout  (<J),  or  with  2-3  scarcely  noticeable  spinules  near 
the  apex  (9  ),  the  inner  carina  with  about  12-14  serrulations  unequally 
placed,  slight,  less  numerous  and  distinctly  slighter  in  the  female  than  in 
the  male,  the  intervening  sulcus  only  moderately  broad.  Hind  tibia?  with 
a  hardly  noticeable  arcuation  or  sinuation  in  the  male,  hardly  (  £ )  or 
much  (  9  )  longer  than  the  femora,  slender,  armed  beneath  with  two 
median  subapical  spines  besides  the  apical  pair;  spurs  subaltern  ate,  the 
basal  at  about  the  end  of  the  proximal  fourth  of  the  tibia,  considerably 
longer  than  the  tibial  depth,  set  at  an  angle  of  about  35°  with  tho 
tibia  and  divaricating  98°-100°,  their  apical  fourth  incurved  ;  inner 
middle  calcaria  considerably  longer  than  the  outer,  more  than  twice  as 
long  as  the  others  or  as  the  spurs,  and  fully  as  long  as  the  first  tarsal 
joint.  Hind  tarsi  about  two  fifths  as  long  as  the  tibiae,  the  first  joint 
longer  than  the  other  joints  together,  the  second  much  more  than 
twice  as  long  as  the  third  and  with  it  longer  than  the  fourth.  Cerci 
stout  at  base,  beyond  slender,  about  as  long  as  the  femoral  breadth. 
Ovipositor  straight,  almost  two  thirds  as  long  as  the  hind  femora,  very 
little  enlarged  at  base,  tapering  almost  throughout  but  very  gently, 
the  tip  upturned  a  little  and  finely  acuminate,  the  armature  as  in

Distinguishable  from  C.  uhleri  by  the  slightly  different  and  weaker 
armature  of  the  carina?  of  the  hind  femora,  but  especially  by  the  slen- 
derer hind  femora,  and  the  narrower  inferior  sulcus  of  the  same.  I 
probably  led  Mr.  Blatchley  into  his  pardonable  error  by  determining 
this  for  him  as  C.  uhleri.

portions,  but  especially  on  the  stouter  part  of  the  femora  beyond  the 
middle  and  within  as  well  as  without,  with  raised  points  closely  crowded, 
the  outer  carina  elevated,  armed  in  the  middle  third  with  a  series  of 
about  five  spines,  sometimes  inequidistant,  distally  increasing  in  length, 
the  last  and  to  some  extent  the  others  bent-arcuate,  about  as  long  as 
the  tibial  spurs  but  coarser,  followed  by  a  rapid  narrowing  of  the 
femora  and  on  this  narrow  portion  by  4-5  minute  serrulations,  the 
inner  carina  pretty  regularly  and  minutely  but  not  closely  spinulate, 
the  intervening  sulcus  broad.  Hind  tibiae  feebly  arcuate,  somewhat 
longer  than  the  femora,  armed  beneath  with  a  single  subapical  spine

This  species  is  very  closely  related  to  C.  uhleri,  differing  in  its 
markings,  which  are  less  sprinkled,  and  in  the  more  pronounced  spinu- 
lations  of  the  hind  femoral  carinae  in  the  male.

24.     CEUTHOPHILUS  NIGRICANS,  sp.  nov. 

Body  glabrous,  blackish  fuscous  with  obscure  rufo-luteous  markings, 
becoming  pallid  luteous  and  more  distinct  on  the  abdomen  ;  they  con- 
sist almost  wholly  of  a  sprinkling  of  small  roundish  spots  and  dots, 
more  profuse  and  elongated  on  the  abdomen,  but  there  is  besides  a 
very  obscure  mediodorsal  line  or  stripe  on  the  pronotum ;  excepting 
on  the  under  surface  of  the  femora,  the  femora  and  tibiae  are  dark 
fuliginous  and  the  outer  side  of  the  hind  femora  very  dark  castaneous, 
heavily  infuscated  in  the  apical  half,  blackish  at  tip,  and  with  deep 
and  heavy  fuscous  scalariform  markings.  The  antennae  are  slender 
and  at  least  in  the  basal  portion  blackish  fuscous,  and  the  legs  are 
rather  short,  though  the  hind  legs  are  relatively  much  longer  in  the 
female  than  in  the  male.  Fore  femora  not  stouter  than  the  middle 
femora,  much  less  than  half  as  long  as  the  hind  femora,  particularly 
in  the  female,  and  very  little  longer  than  the  pronotum,  the  inner 
carina  with  one  or  two  short  spines.  Middle  femora  similarly  armed 
on  the  front  carina,  the  hind  carina  with  one  or  two  spines  besides  a 
short  genicular  spine.  Hind  femora  shorter  (^)  or  longer  (9)  than 
the  body,  somewhat  more  than  twice  ($)  or  about  three  times  (9)  as 
long  as  the  fore  femora,  in  the  male  stout  and  tapering  pretty  regularly 
to  the  genicular  lobes,  about  two  and  three  quarters  times  longer  than 
broad,  the  middle  of  the  distal  half  of  the  inner  surface  above  with  a 
small  cluster  of  raised  points,  in  the  female  much  slenderer  and  with 
the  apical  fourth  subequal,  the  outer  carina  uniformly  elevated,  deli- 
cately serratulo-spinous  through  most  of  its  extent  ((£),  or  with  a  few 
distant  spinules  in  the  outer  half  (9),  the  inner  carina  armed  as  the 
outer  but  somewhat  more  delicately  (c?)  or  with  a  few  raised  points 
(9  ),  the  intervening  sulcus  moderate.  Hind  tibiae  somewhat  longer 
than  the  femora,  straight  in  both  sexes,  armed  beneath  with  a  single 
subapical  spine  besides  the  apical  pair ;  spurs  subopposite,  the  basal

divaricating  about  90°,  faintly  incurved ;  inner  middle  calcaria  much 
longer  than  the  outer,  nearly  twice  as  long  as  the  others  or  as  the 
spurs,  but  much  shorter  than  the  first  joint  of  the'  tarsus.  Hind 
tarsi  not  much  less  than  half  as  long  as  the  tibiae,  the  first  joint  almost 
as  long  as  the  rest  together,  the  second  twice  as  long  as  the  third  and 
with  it  as  long  as  the  fourth.  Cerci  very  short  and  not  very  slender. 
Ovipositor  about  a  fifth  longer  than  the  fore  femora,  straight,  not 
stout  and  delicately  tapering  iu  basal  half,  the  tip  upturned  and  very 
acuminate,  the  teeth  of  the  inner  valves  aculeate,  straight.

The  single  9  has  but  one  hind  leg,  and  this  has  been  attached 
after  breaking  off.  As  the  leg  seems  to  be  abnormally  different  from 
that  of  the  cf,  it  is  quite  possible  that  it  does  not  belong  to  this 
specimen,  and  that  the  characters  given  above  drawn  from  it  should 
be  eliminated. 

25.     CEUTHOPHILUS  FDSIFORMIS,  sp.  nov. 

Body  testaceous  almost  wholly  overlaid  with  black  above,  the 
abdomen  wholly,  the  meso-  and  metanotum  all  but  an  anterior  mesial 
spot,  and  the  prouotum  to  such  a  degree  that  the  testaceous  is  confined 
to  a  large  equilateral  triangular  patch  on  each  side,  the  inferior  mar- 
gins for  their  base  and  a  couple  of  small  mesial  patches,  the  larger 
behind;  the  lower  half  of  the  sides  throughout,  however,  is  pallid 
testaceous ;  the  legs  are  testaceous  and  uniform  except  for  rather  faint 
fuscous  scalariform  markings  on  the  hind  femora.  The  antennae  are 
slender  and  about  three  times  as  long  as  the  very  compact  body,  and 
the  legs  short  and  not  very  slender.  Fore  femora  distinctly  stouter 
than  the  middle  femora,  somewhat  less  than  half  as  long  as  the  hind 
femora  and  but  little  longer  than  the  pronotum,  the  inner  carina 
armed  only  with  a  strong  subapical  spine.  Middle  femora  armed  with 
2-3  spines  on  the  front  carina,  the  distal  scarcely  or  no  longer  than 
the  others,  and  on  the  hind  carina  2-3  spines  besides  a  moderate 
genicular  spine.  Hind  femora  as  long  as  the  body,  a  little  more  than 
twice  as  long  as  the  fore  femora,  very  stout,  the  subequal  apical  por-

arrangement,  the  intervening  sulcus  rather  broad.  Hind  tibiae 
straight,  shorter  than  the  femora,  armed  beneath  with  a  single  sub- 
apical  spine  besides  the  apical  pair ;  spurs  subopposite,  the  basal  at

as  the  tibial  depth,  set  at  au  angle  of  about  55°  with  the  tibia  and 
divaricating  about  100°,  their  extreme  tips  incurved;  inner  middle 
calcaria  barely  longer  than  the  outer,  half  as  long  again  as  the  others 
or  as  the  spurs,  and  a  little  shorter  than  the  first  tarsal  joint.  Hind 
tarsi  almost  half  as  long  as  the  tibia?,  the  first  joint  about  as  long  as 
the  rest  together,  the  second  fully  twice  as  long  as  the  third  and  with

Dark  mahogany  brown,  glabrous,  marked  with  reddish  luteous  in  a 
more  regular  pattern  than  common,  there  being  a  moderately  broad 
mesial  stripe  of  the  brighter  color,  broader  on  the  anterior  than  the 
posterior  part  of  the  segments,  the  sides  with  regularly  disposed  flecks 
and  dots  of  luteous,  becoming  more  numerous  below,  so  that  the  luteous 
prevails  on  the  lower  portion  of  the  sides  ;  on  the  abdomen  the  luteous 
spots  are  usually  either  circular  or  made  of  short  oblique  dashes ;  the 
legs  are  as  dark  as  the  upper  surface,  the  hind  femora  with  the  usual 
pattern,  but  the  lighter  portions  subdued  in  tint.  The  legs  are  rather 
short,  the  antennae  not  stout.  Fore  femora  stouter  than  the  middle

of  which  excepting  at  base  is  increasingly  fuscous  distally  and 
broadly  annulate  with  blackish  apically,  the  surface  generally  sprinkled 
with  luteous  dots,  with  faintly  different  depths  of  color  marking  a 
scalariform  pattern.  The  hind  tibial  spines  are  distinctly  blackish 
at  the  base.  The  antennae  are  about  three  times  as  long  as  the  body, 
luteous,  the  joints  at  first  feebly  infuscated  at  the  base,  afterwards 
wholly,  and  then  interrupted  by  luteous  for  a  single  joint  every  few 
joints  irregularly,  the  legs  moderately  slender  and  not  very  long,  the

no  longer  than  the  femora,  straight  in  both  sexes,  slender,  generally 
armed  beneath  with  two  median  subapical  spines  besides  the  apical 
pair ;  spurs  irregularly  opposite,  the  basal  at  the  end  of  the  proximal 
third  of  the  tibia,  slightly  longer  than  the  tibial  depth,  set  at  an  angle  of 
about  45°  with  the  tibia  and  divaricating  about  1 20°,  slightly  incurved

more  than  twice  as  long  as  the  others  or  as  the  spurs,  and  as  long  as 
the  first  tarsal  joint.  Hind  tarsi  about  two  fifths  as  long  as  the  hind 
tibiae,  the  first  joint  as  long  as  the  rest  together,  the  second  more  than

about  two  thirds  as  long  as  the  hind  femora,  straight,  gently  tapering 
in  the  proximal,  rather  slender  and  equal  in  the  distal  half,  the  tip 
upturned  and  acute  but  not  aculeate,  the  armature  of  the  inner  valves

luteous,  the  hind  pair  externally  striped  with  clearer  luteous  above 
and  spotted  below ;  hind  femoral  geniculations  blackish ;  all  the  tibias 
and  antennae  dark  luteous.  The  antennae  are  moderately  slender,  the 
legs  rather  long.  Fore  femora  scarcely  stouter  than  the  middle 
femora,  fully  one  fourth  longer  than  the  pronotum  but  only  two  fifths 
the  length  of  the  hind  femora,  the  inner  carina  with  two  spines,  the 
outer  of  which  is  hardly  subapical  but  pretty  stout.  Middle  femora 
with  three  pretty  stout  spines  on  the  front  carina,  and  on  the  hind 
carina  from  1-4  small  spines  besides  a  long  genicular  spine.  Hind 
femora  of  the  length  of  the  body,  about  two  and  a  half  times  as 
long  as  the  fore  femora,  very  stout,  the  apical  fourth  subequal,  about 
three  and  a  quarter  times  as  long  as  broad  ;  the  upper  half  very 
faintly  but  closely  scabrous  in  the  darker  portions,  the  outer  carina 
elevated,  with  5-6  unequal  and  inequidistant  large  or  very  large 
spines,  the  largest  just  beyond  the  middle,  coarse,  especially  at  base, 
and  much  longer  than  the  tibial  spurs,  besides  one  or  two  spinules 
in  the  constricted  portion  of  the  femora,  the  inner  carina  rather  dis- 
tantly and  rather  regularly  spiuulate  throughout,  the  intervening  sulcus 
very  broad.  Hind  tibia?  gently  arcuate  on  basal  third,  much  longer 
than  the  femora,  not  very  slender,  armed  beneath  apically  with  two  or 
three  spines  besides  the  apical  pair ;  spurs  subalternate,  the  basal  at 
end  of  proximal  third  of  the  tibia,  slightly  longer  than  the  tibial  depth, 
set  at  an  angle  of  45°  with  the  tibia  and  divaricating  about  100°,  the 
apical  half  incurved ;  (calcaria  and  hind  tarsi  lost  in  the  only  specimen 
known).  Cerci  slender,  gently  tapering,  about  two  thirds  as  long  as 
the  femoral  breadth.

Ceuthophilus  maculatus  (pars),  Scudd.!,  Bost.  Journ.  Nat.  Hist.,  vii. 
434  (1862). 

Glabrous,  castaneous,  more  or  less,  often  deeply,  infuscated  especially 
above,  the  infuscation  often  but  not  always  terminating  below  the 
middle  of  the  sides,  which  are  there  sordid  luteous ;  a  broad  more  or 
less  and  often  very  obscure  mediodorsal  rufo-luteous  stripe  on  the 
pronotum,  sometimes  extended  farther  back  but  then  generally  broken  ; 
the  sides  of  the  pronotum  and  to  a  lesser  extent  the  meso-  and  meta- 
notum  are  more  or  less  blotched  or  vermiculate  with  luteous,  and  the 
abdomen  is  more  or  less  but  generally  feebly  maculate  with  luteous  ; 
the  markings  and  the  coloring  vary  greatly,  so  that  it  is  difficult  to  for- 
mulate any  general  statement;  the  female  is  apt  to  be  darker  than  the 
male,  and  specimens  from  New  England  are  often  almost  uniformly 
dark,  even  almost  black,  while  the  contrasts  between  the  dorsum  and 
the  lower  portion  of  the  sides  are  strongest  in  specimens  from  the 
Middle  Atlantic  States,  where  they  grow  to  a  large  size  ;  the  legs  are 
generally  luteo-castaneous,  the  tips  of  all  the  femora  dark,  sometimes 
almost  black,  the  hind  femora  with  scalariform  fuscous  markings. 
The  antennas  are  not  often  infuscated  and  then  generally  more  or  less 
or  feebly  annulate  with  luteous,  slender  and  generally  2—3  times  as 
long  as  the  body,  the  legs  rather  slender  and  moderately  short. 
Fore  femora  scarcely  stouter  than  the  middle  femora,  considerably  less 
than  half  as  long  as  the  hind  femora  and  but  very  little  longer  than  the 
pronotum,  the  inner  carina  with  a  subapical  spine,  rarely  accompa- 
nied by  another.  Middle  femora  with  1-3  spines  (largely  depending 
upon  age)  on  the  front  carina,  and  on  the  hind  carina  0-3  spines 
besides  a  longer  but  short  genicular  spine.  Hind  femora  two  and  a 
quarter  times  longer  than  the  fore  femora,  about  as  long  as  the  body, 
stout  and  tumid,  the  upper  and  lower  margins  almost  equally  arcuate, 
scarcely  more  than  the  genicular  portion  subequal,  almost  three  times 
as  long  as  broad,  the  inner  surface  with  a  very  few  raised  points  next 
or  at  the  upper  margin  beyond  the  middle,  scarcely  perceptible  or 
absent  from  the  female,  the  outer  carina  minutely,  closely,  and  pretty 
uniformly  serrulate  through  all  but  the  basal  third,  sometimes  almost 
imperceptible  in  the  female,  the  inner  carina  a  feebler  repetition  of  the 
outer,  the  intervening  sulcus  moderate  in  width.  Hind  tibiae  slender,

straight  in  both  sexes,  barely  or  no  longer  than  the  femora,  armed 
beneath  with  1-2  subapical  spines  besides  the  apical  pair ;  spurs  sub- 
opposite,  the  basal  at  the  end  of  the  proximal  third  of  the  tibia, 
scarcely  shorter  than  the  tibial  depth,  set  at  an  angle  of  about  45° 
with  the  tibia  and  divaricating  about  100-110°,  their  tips  incurved; 
inner  middle  calcaria  considerably  longer  than  the  outer,  about  twice 
as  long  as  the  others  or  as  the  spurs,  but  shorter  than  the  first  tarsal 
joint.  Hind  tarsi  almost  two  fifths  as  long  as  the  tibiae,  the  first  joint 
not  so  long  as  the  rest  together,  the  second  considerably  more  than 
twice  as  long  as  the  third  and  with  it  fully  as  long  as  the  fourth. 
Cerci  moderately  stout,  tapering  rather  uniformly,  about  two  thirds 
as  long  as  the  femoral  breadth.  Ovipositor  half  as  long  as  the  hind 
tibiae,  straight,  tapering  in  basal  half,  equal  and  moderately  slender, 
the  tip  slightly  upcurved  and  acutely  pointed  (about  35°),  the  inner 
valves  with  aculeate,  scarcely  arcuate  teeth.

Color  and  markings  almost  precisely  the  same  as  in  G.  terrestris,  so 
that  imperfect  and  immature  specimens  are  exceedingly  difficult  to 
separate ;  but  the  darker  markings  in  this  species  are  as  a  rule  darker 
and  cover  the  surface  to  a  greater  extent,  and  when  the  mediodorsal 
stripe  is  present  it  is  often  broader  and  extends  upon  the  meso-  and 
metanotum  ;  on  the  other  hand,  the  maculation  of  the  abdomen  with 
luteous  is  usually  more  striking  in  the  present  species  (partly  from 
the  darkness  of  the  ground)  and  forms  sometimes  a  tolerably  regular 
pattern,  consisting  on  each  joint  of  an  anterior  mediodorsal  triangular 
spot,  a  central  subdorsal  oblique  dash,  and  posterior  spots  farther  from 
the  middle  line.  The  antennae  are  from  two  to  three  times  as  long  as 
the  body,  and  slender  except  at  extreme  base,  and  the  legs  are 
moderately  long.  Fore  femora  no  stouter  than  the  middle  femora,  a 
little  more  than  a  fourth  longer  than  the  pronotum  and  much  less  than 
half  as  long  as  the  hind  femora,  the  inner  carina  with  a  long  subapical 
spine  and  occasionally  an  additional  one.  Middle  femora  with  0-2 
spines  besides  a  rather  long  subapical  spine  on  the  front  carina,  and 
on  the  hind  carina  an  occasional  small  spine  besides  a  long  genicular 
spine.  Hind  femora  of  about  the  length  of  the  body,  three  and  a  half 
times  as  long  as  broad,  about  two  and  a  third  times  as  long  as  the  fore 
femora,  moderately  stout  at  base,  the  distal  fifth  subequal,  with  no 
raised  points  on  the  upper  or  inner  surface,  the  outer  carina  with 
about  thirteen  unequal  coarse  spines,  the  longest  hardly  half  as  long  as 
the  tibial  spurs  (£)or  with  minute  distant  inconspicuous  spinules  (9),

the  inner  carina  with  similar  but  uniform  spinulation,  none  so  large 
as  on  the  outer  carina  (<J)  or  with  a  few  minute  spinules  on  the 
apical  half  (9),  the  intervening  sulcus  not  very  broad.  Hind  tibiae 
feebly  undulate  in  the  basal  half  in  the  male,  slender  in  both  sexes,  dis- 
tinctly but  not  greatly  longer  than  the  femora,  armed  beneath  with  a 
single  preapical  spine  or  occasionally  with  two  minute  unaligned 
spines  besides  the  apical  pair ;  spurs  rudely  opposite,  the  basal  at  the 
end  of  the  proximal  third  of  the  tibia,  more  than  half  as  long  again  as 
the  tibial  depth,  set  at  an  angle  of  about  40°  with  the  tibia  and  divari- 
cating 90-100°,  their  tips  incurved ;  inner  and  outer  middle  calcaria 
subequal,  more  than  twice  as  long  as  the  others  or  as  the  spurs,  and  as 
long  as  the  first  tarsal  joint.  Hind  tarsi  about  two  fifths  as  long  as 
the  tibiae,  the  first  joint  shorter  than  the  rest  together,  the  second  twice 
as  long  as  the  third  and  with  it  longer  than  the  fourth.  Cerci  stout 
in  the  proximal  half,  tapering  beyond,  about  two  thirds  as  long  as  the 
femoral  breadth.  Ovipositor  nearly  two  thirds  as  long  as  the  hind

tiuge ;  the  markings  consist  of  a  mediodorsal  stripe  of  varying  width 
but  usually  rather  broad  on  the  prouotum,  especially  a  little  before 
either  border,  generally  reduced  to  a  line  on  the  abdomen,  a  large 
lateral  patch  on  either  side  of  the  pronotum,  sometimes  confined  to  the 
inferior  margin,  sometimes  extending  half  way  to  the  mediodorsal  line, 
and  a  conspicuous  and  liberal  sprinkling  of  roundish 'spots,  generally 
more  or  less  elongated  longitudinally,  especially  on  the  abdomen  ;  the 
antennae  are  pale  fuscous  and  the  legs  sordid  luteous  more  or  less 
infuscated,  the  hind  femora  with  heavy  fuscous  scalariform  markings, 
leaving  roundish  dull  luteous  spots  in  the  openings  of  the  upper  half. 
The  antennae  are  slender  and  apparently  only  about  twice  the  length 
of  the  body  or  a  little  more,  and  the  legs  short  though  slender.  Fore 
femora  of  the  same  slenderness  as  the  middle  femora,  much  less  than 
half  as  long  as  the  hind  femora  and  a  little  more  (<J)  or  a  little 
less  (9)  than  a  fourth  longer  than  the  pronotum,  the  inner  carina  with 
1-2  small  spines.  Middle  femora  with  1—3  spines  on  the  front  carina, 
the  subapical  the  longest  but  not  long,  the  hind  carina  with  rarely 
more  than  the  moderately  short  genicular  spine.  Hind  femora  some- 
what shorter  than  the  body,  about  two  and  a  half  times  longer  than 
the  fore  femora,  moderately  slender,  being  about  three  and  a  third 
times  as  long  as  broad,  fully  the  apical  fourth  subequal,  the  surface 
with  no  raised  spines,  the  outer  carina  with  a  few  distant  serrations 
or  recumbent  spines  on  apical  half  (<£)  or  unarmed  (9),  the  inner 
carina  similar  to  the  outer,  the  intervening  sulcus  narrow.  Hind 
tibiae  straight  in  both  sexes,  not  a  great  deal  longer  than  the  femora, 
armed  beneath  with  a  single  subapical  spine  besides  the  apical  pair ; 
spurs  subalternate,  the  Sasal  at  the  end  of  the  proximal  third  of  the 
tibia,  scarcely  if  any  longer  than  the  tibial  depth,  set  at  an  angle  of  45° 
with  the  tibia  and  divaricating  about  110°,  their  tips  incurved  ;  inner 
middle  calcaria  much  longer  than  the  outer,  more  than  twice  as  long 
as  the  others  or  as  the  spurs,  and  nearly  as  long  as  the  first  joint  of 
the  tarsus.  Hind  tarsi  fully  two  fifths  as  long  as  the  tibiae,  the  first 
joint  almost  as  long  as  the  rest  together,  the  second  twice  as  long  as 
the  third  and  with  it  fully  as  long  as  the  fourth.  Cerci  slender,  taper- 
ing regularly,  three  fourths  as  long  as  the  femoral  breadth.  Ovipositor 
as  long  as  the  fore  femora,  straight,  the  apical  three  fifths  equal  and 
moderately  slender,  the  apex  a  little  upturned  and  subacute  but  not 
very  much  produced,  the  teeth  of  the  inner  valves  consisting  of  blunt 
pointed  crenations.

32.     CEUTHOPHILUS  BICOLOR,  sp.  nov. 

Body  glabrous,  luteo-testaceous,  with  a  broad  subdorsal  blackish 
fuscous  band  on  either  side,  leaving  between  them  a  broad  bright  stripe 
the  whole  length  of  the  body,  next  the  stripe  sharply  delimited,  later- 
ally more  or  less  broken,  ragged  and  fading  away,  narrow  on  the  pro- 
notum  where  it  is  infringed  upon  by  a  large  central  luteous  spot  on 
the  sides,  broader  and  profusely  spotted  with  luteous  posteriorly,  the 
lower  portions  of  the  sides  almost  wholly  pallid  luteous  with  cloudy 
infuscations,  the  extreme  margin  testaceous ;  legs  luteo-testaceous,  the 
hind  femora  feebly  marked  with  fuscous  in  a  scalariform  pattern  and 
tipped  with  fuscous.  The  antennas  are  slender  and  at  least  three  times 
as  long  as  the  body,  and  the  legs  slender  and  rather  short.  Fore 
femora  no  stouter  than  the  middle  pair,  much  less  than  half  as  long 
as  the  hind  femora,  a  fifth  as  long  again  as  the  pronotum,  the  inner 
cariua  with  two  or  three  spines,  the  preapical  much  longer  than 
the  others.  Middle  femora  with  the  front  carina  similarly  armed

Ceuthophilus  nodulosus  Brunn.,  Monogr.  Stenop.,  64,  fig.  33a  (1888). 

Luteo-castaneous,  heavily  marked  with  blackish  fuscous  especially 
along  the  posterior  borders  of  all  the  segments  and  the  anterior  border 
of  the  pronotum,  and  the  latter  also  flecked  with  it  in  an  obscure 
fashion  upon  the  whole  disk ;  legs  luteous,  the  hind  femora  almost 
lacking  the  usual  scalariform  markings.  The  antennae  are  slender, 
but  are  apparently  less  than  twice  the  length  of  the  body,  the  legs 
short.  Fore  femora  very  slightly  stouter  than  the  middle  femora, 
slightly  (  J  )  or  no  ( 9  )  longer  than  the  pronotum  and  distinctly  less 
than  half  as  long  as  the  hind  femora,  the  inner  carina  with  a  feeble 
subapical  spine,  at  least  in  the  male.  Middle  femora  generally  with 
3-4  small  spines  on  the  front  carina,  and  on  the  hind  carina  0-1  (  9  ) 
or  3-8  ((£)  short  spines  besides  a  short  genicular  spine.  Hind  femora 
pretty  stout,  a  very  brief  apical  portion  equal,  a  little  less  than  three 
times  as  long  as  broad,  considerably  more  than  twice  as  long  as  the 
fore  femora,  all  the  scalariform  dark  portions  of  the  surface,  especially 
in  the  male,  scabrous  with  raised  points,  which  are  also  clustered  about 
the  upper  portion  of  the  inner  side  just  beyond  the  middle,  the  outer 
carina  elevated,  with  three  or  four  inequal  and  irregularly  distant 
large  and  rather  coarse  more  or  less  arcuate  spines,  the  longest  nearly 
or  quite  as  long  as  the  tibial  depth,  placed  in  the  middle  half,  besides 
a  few  minor  spines  beyond  them  (<£)  or  with  4—5  small  distant  spines, 
most  of  them  in  the  constricted  part  of  the  femora  (9),  the  inner 
cariua  with  a  series  of  closer  but  in  no  way  crowded  smaller  and  uni- 
form spinules,  subobsolete  in  the  female,  the  intervening  sulcus  moderate 
in  breadth.  Hind  tibiae  strongly  bent  or  bowed  near  the  middle  and 
subsinuate,  on  the  middle  of  the  proximal  half  compressed  to  form  a 
triangular  denticle  on  the  under  surface,  from  which  a  regular  curve

spines  (in  the  $  arising  from  slight  elevations)  besides  the  apical  pair ; 
spurs  subopposite,  the  basal  well  beyond  the  end  of  the  distal  third  of 
the  tibia,  hardly  more  than  half  as  long  as  the  tibial  depth,  set  at  an 
angle  of  about  45°  with  the  tibia  and  divaricating  about  as  much ; 
inner  middle  calcaria  somewhat  longer  than  the  outer,  twice  as  long 
as  the  others  or  as  the  spurs  but  much  shorter  than  the  first  tarsal 
joint.  Hind  tarsi  less  than  two  fifths  the  length  of  the  tibiae,  the  first 
joint  nearly  as  long  as  the  rest  together,  the  second  fully  twice  as  long 
as  the  third  and  with  it  as  long  as  the  fourth.  Cerci  very  short,  not 
very  slender,  rapidly  tapering,  hardly  more  than  half  as  long  as  the 
femoral  breadth  (9)  or  developed  basally  as  a  single  stout  sub- 
clavate  apically  upturned  blunt  joint,  surmounted  by  a  brief  conical 
multiarticulate  appendage,  the  only  portion  which  surpasses  the  supra- 
anal  plate  (<J).  Ovipositor  brief  and  slight,  no  longer  than  the  fore 
femora,  tapering  in  proximal,  equal  in  distal  half,  the  apex  and  arma-

34.    CEUTHOPHILUS  VALGUS,  sp.  nov. 

Dark  luteo-testaceous,  more  or  less  infuscated  especially  along  the 
hind  borders  of  all  the  segments  and  the  front  border  of  the  pronotum  ; 
occasionally  a  few  indistinct  luteous  dots  occur  in  a  transverse  series 
on  the  abdominal  segments,  but  most  of  the  varied  markings  are  con- 
fined to  the  pronotum,  where  they  are  not  pronounced  and  consist  of 
a  dull  luteous  mediodorsal  stripe  and  vague  and  irregular  streaks  or 
clouds  of  luteous  upon  either  side,  more  or  less  extensive ;  the  legs 
are  generally  lighter  than  the  body,  but  are  more  or  less  infuscated 
beyond  the  base  of  the  femora,  the  hind  pair  of  which  scarcely  show 
any  scalariform  markings.  The  antennae  are  not  very  slender,  two  to 
three  times  as  long  as  the  body,  and  the  legs  are  moderately  long  and

curved ;  inner  middle  calcaria  about  a  third  longer  than  the  outer, 
twice  as  long  as  the  others  or  as  the  spurs,  but  hardly  more  than  half 
as  long  as  the  first  tarsal  joint.  Hind  tarsi  less  than  half  as  long  as

Obscure  brownish  fuscous,  with  luteous  markings  which  are  very 
dull  and  inconspicuous  except  in  the  bordering  of  the  inferior  margins 
of  the  thoracic  segments ;  they  are  mostly  found  in  large  blotches  of 
very  irregular  form  on  the  sides  of  the  pronotum  and  in  smaller  lateral 
and  dorsal  anterior  spots  on  the  other  segments,  sometimes  confluent 
and  the  lateral  often  crossing  the  abdominal  segments ;  there  is  some- 
times an  interrupted  mediodorsal  thread  ;  legs  luteous,  much  infuscated 
especially  on  either  side  of  the  femoro-tibial  articulation,  the  hind 
femora  very  broadly  marked  with  blackish  fuscous  in  a  scalariform

from  the  anterior  margins  in  a  pair  of  large  subdorsal  stripes,  the 
fuscous  portions  often  dotted  with  distinct  luteous  dots.  The  hind 
femora  are  marked  in  the  usual  compound  scalariform  manner  with 
fuscous,  which  unites  distally  in  two  elongate  patches  on  the  lower  half 
of  the  outer  surface.  Antennae  more  than  twice  as  long  as  the  body, 
not  very  slender.  Legs  moderately  long.  Fore  femora  distinctly

Very  pallid  luteous,  marked  with  fuscous  and  blackish  fuscous,  the 
latter  in  the  posterior  bordering  of  all  the  segments,  the  former  in 
obscure  blotches  on  the  pronotum  and  along  its  front  margin,  more 
obscure  in  some  specimens  than  in  others;  a  mediodorsal  luteous 
thread  breaks  most  of  the  fuscous  markings  of  the  body ;  the  legs  are 
very  pallid  luteous,  sometimes  infuscated  on  the  distal  portions  of  the 
femora  and  especially  in  scalariform  markings,  never  deep,  upon  the 
hind  femora ;  the  spines  of  the  legs  are  all  dusky  tipped  ;  eyes  black. 
The  antenme  are  slender  and  from  twice  to  thrice  the  length  of  the

Of  mingled  fuscous  and  luteo-castaneous,  sometimes  one,  sometimes 
the  other  prevailing ;  when  it  is  the  latter,  the  fuscous  shows  itself  on 
either  side  of  the  mediodorsal  line  in  a  series  of  subtriangular  sub- 
dorsal  patches  seated  upon  the  posterior  margin  of  the  segments,  much 
larger  on  the  thoracic  than  on  the  abdominal  and  partially  or  wholly 
absent  from  some  of  the  latter ;  besides  there  is  a  series  of  lateral 
blotches,  just  failing  to  reach  the  lower  margins  of  the  nota  and  more 
extended  on  each  segment  anteriorly  than  posteriorly ;  on  the  pro- 
notum these  two  sets  blend  irregularly,  so  that  here  the  darker  colors 
prevail ;  the  hind  femora  are  more  or  less  infuscated  with  the  mark- 
ings common  to  the  genus,  more  or  less  distinct,  the  geniculations 
laterally  blackish.  Antennae  moderately  stout.  Legs  not  very  elongate. 
Fore  femora  basally  somewhat  stouter  than  the  middle  femora,  con- 
siderably less  than  half  as  long  as  the  hind  femora,  about  a  fourth 
longer  than  the  pronotum,  the  inner  carina  with  2-3  spines,  the  sub- 
apical  and  sometimes  one  or  both  the  others  pretty  large.  Middle 
femora  with  the  front  carina  as  in  the  fore  femora,  the  hind  carina 
with  1—2  spines  near  the  middle  besides  a  very  long  genicular  spine. 
Hind  femora  a  little  shorter  than  the  body,  considerably  more  than 
twice  as  long  as  the  fore  femora,  very  stout  and  broad,  being  con- 
siderably less  than  three  times  as  long  as  broad,  with  a  preapical 
broad  constriction,  so  that  the  distal  fourth  is  subequal,  the  apical  half 
covered  very  sparsely  except  beneath  with  raised  spiuous  points

as  long  as  the  rest  together,  the  second  more  than  twice  as  long  as  the 
third  and  with  it  as  long  as  the  fourth.  Cerci  pretty  stout  at  base, 
tapering  delicately,  probably  as  long  as  the  femoral  breadth  (broken  in

less  distinctly  connected  by  a  luteous  thread ;  on  the  middle  of  each 
side  of  each  segment  a  transverse  dash,  on  the  abdominal  segments 
more  elongated  than  on  the  thoracic,  and  generally  partly  merged  in 
the  mediodorsal  spot,  on  the  pronotum  larger  than  elsewhere  and  ac- 
companied by  some  outlying  dots ;  also  as  an  inferior  margining  of  the 
thoracic  segments  ;  but  all  these  markings  may  become  so  enlarged  as  to 
make  the  surface  prevailingly  luteous  ;  the  femora  are  fuscous,  becom- 
ing lutescent  toward  the  base,  on  the  hind  pair  as  heavy  scalariform 
markings,  on  the  anterior  pairs  as  slender  stripes.  The  antennae  are 
brownish  luteous,  rather  slender  and  apparently  about  three  times 
the  length  of  the  body,  the  legs  rather  short  and  slender.  Fore 
femora  no  stouter  than  the  middle  femora,  less  than  a  fourth  longer 
than  the  pronotum,  much  less  than  half  as  long  as  the  hind  femora,

some  very  distant  and  very  slight  serrulations,  the  intervening  sulcus 
slender.  Hind  tibiae  straight  in  both  sexes,  distinctly  longer  than  the 
femora,  slender,  armed  beneath  with  a  single  preapical  spine  besides 
the  apical  pair ;  spurs  subopposite,  fully  twice  as  long  as  the  tibial 
depth,  set  at  an  angle  of  about  35-45°  with  the  tibia,  and  divaricating 
about  90-100°,  their  tips  considerably  incurved  ;  inner  middle  calcaria 
scarcely  longer  than  the  outer,  more  than  twice  as  long  as  the  others, 
nearly  twice  as  long  as  the  spurs  and  about  as  long  as  the  first  tarsal

Body  bright  luteous,  heavily  marked  with  blackish  fuscous ;  on  the 
pronotum  the  markings  are  very  irregular,  but  consist  in  the  main  of 
the  following :  on  either  side  of  the  front  margin  a  large  transverse 
fuscous  spot,  which  reaches  neither  the  mediodorsal  line  nor  the  lateral 
margin  and  is  interrupted  below  by  a  roundish  spot  and  above  by  the 
incursion  from  the  anterior  margin  of  a  short  narrowing  dash;  in 
the  middle  of  the  dorsum  a  quadrate  spot  divided  by  a  mediodorsal 
luteous  line  into  a  pair  of  longitudinal  bars,  each  connected  anteriorly 
with  the  before  mentioned  anterior  spot,  and  leaving  a  luteous  sub- 
marginal  anterior  mediodorsal  spot ;  an  infero-posterior  black  spot  not 
touching!  the  margin ;  and  a  laterodorsal  subtriangular  spot  on  the 
posterior  margin ;  on  the  succeeding  thoracic  segments,  and  on  the 
abdominal  there  is  a  series  of  large  irregularly  triangular  laterodorsal 
spots  on  the  posterior  margins,  and  another  lateral  series  of  roundish 
or  transverse  spots  generally  not  reaching  any  margin ;  the  legs  are 
luteous,  the  fore  and  middle  femora  more  or  less  infuscated  in  longi-

the  body,  the  legs  moderately  long.  Fore  femora  scarcely  stouter 
than  the  middle  femora,  less  than  a  fifth  longer  than  the  pronotum, 
much  less  than  half  as  long  as  the  hind  femora,  the  inner  carina  with 
a  tolerably  long  subapical  spine  sometimes  accompanied  by  another 
minute  one.  Middle  femora  with  a  long  subapical  spine  on  the  front 
carina,  accompanied  at  least  in  the  male  by  a  couple  of  others  smaller, 
and  on  the  hind  carina  one  or  two  short  spines  at  least  in  the  male, 
accompanied  by  a  long  genicular  spine.  Hind  femora  moderately

the  cf ,  the  intervening  sulcus  moderate.  Hind  tibia?  straight  in  both 
sexes,  slightly  longer  than  the  femora,  armed  beneath  with  a  single 
subapical  spine,  besides  the  apical  pair ;  spurs  subalternate,  the  basal 
near  the  end  of  the  proximal  fourth  of  the  tibia,  about  half  as  long 
again  as  the  tibial  depth,  set  at  a  varying  angle  with  the  tibia,  the 
outer  series  at  least  in  the  £  being  directed  outward,  the  inner  series 
both  inward  and  posteriorly,  divaricating  about  120°,  the  tips  incurved  ; 
inner  middle  calcaria  considerably  longer  than  the  outer,  more  than 
twice  as  long  as  the  others  or  as  the  spurs,  and  nearly  as  long  as  the

markings.  Antennae  very  slender,  two  or  three  times  as  long  as  the 
body,  the  legs  short.  Fore  femora  slightly  broader  than  the  middle 
femora,  a  very  little  longer  than  the  pronotum  (relatively  longer  in  the

spines  on  the  front  carina,  and  on  the  hind  carina  generally  four  spines 
besides  a  moderately  long  genicular  spine.  Hind  femora  moderately 
slender,  tapering  with  almost  exact  regularity  to  the  tip,  somewhat 
more  than  three  times  as  long  as  broad,  rather  less  than  twice  as  long 
as  the  fore  femora,  the  surface  just  beyond  the  middle  with  very

Varying  from  light  to  dark  castaneous  with  very  feeble  markings, 
excepting  usually  a  greater  or  less  degree  of  infuscatiou  along  the 
posterior  margins  of  all  the  segments  and  the  anterior  margin  of  the 
pronotum  ;  the  pronotum  is  also  sometimes  feebly  enlivened  with  ver- 
iniculate  fuliginous  markings  and  not  infrequently  a  faint  luteous  line 
may  be  traced  along  the  middle  of  the  dorsum,  often  conspicuous  on 
the  pronotum  and  always  slender ;  the  legs  are  concolorous  with  the 
body.  The  antennae  are  rather  coarse,  tapering  throughout  uniformly, 
the  eyes  small,  distinctly  smaller  than  the  anteunal  scrobes,  the  legs 
short  and  stouter  than  usual.  Fore  femora  distinctly  stouter  than  the 
middle  femora,  arched  superiorly,  about  a  fifth  longer  than  the  prono- 
tum and  slightly  more  than  half  as  long  as  the  hind  femora,  the  inner 
carina  with  a  single  subapical  spine  besides  being  minutely  serrulate 
throughout.  Middle  femora  having  a  variable  number  of  spines  but 
usually  3-4  on  the  front  carina,  and  on  the  hind  carina  a  variable  but 
generally  considerable  number  of  minute  spines  or  serrations  besides 
a  short  genicular  spine.  Hiud  femora  about  two  thirds  as  long  as  the 
body  (<£)  or  a  little  less  than  that  (9),  almost  twice  as  long  as  the 
fore  femora,  moderately  stout,  regularly  tapering  to  the  very  apex  with 
no  pregenicular  constriction,  about  three  times  as  long  as  broad, 
glabrous,  with  a  few  feeble  distant  raised  points  above  just  before  the 
geniculation,  the  outer  carina  uniformly  and  rather  delicately  serrulate 
except  at  base,  more  feebly  in  the  female  than  in  the  male,  the  inner 
carina  similarly  but  more  delicately  serrulate,  the  intervening  sulcus 
tolerably  broad  apically  but  not  at  base.  Hind  tibiae  of  male  straight, 
unusually  stout,  on  the  upper  surface  twice  as  broad  in  the  middle  as  at 
base,  of  the  same  length  as  the  femora,  armed  beneath  with  a  single 
preapical  spine  besides  the  apical  pair ;  spurs  subopposite,  about  equal 
to  or  a  little  longer  than  the  tibial  depth,  set  at  an  angle  of  about  45°  to 
the  tibia  and  diverging  at  an  angle  of  60°  or  less  with  each  other,  their 
tips  incurved ;  inner  middle  calcaria  slightly  longer  than  the  outer, 
half  as  long  again  as  the  other  calcaria,  twice  as  long  as  the  spurs  and 
nearly  as  long  as  the  first  joint  of  the  tarsus.  Hind  tarsi  nearly  half 
as  long  as  the  tibiae,  the  first  joint  nearly  as  long  as  the  others  com- 
bined, the  second  twice  as  long  as  the  third  and  with  it  not  so  long  as 
the  fourth.  Cerci  rather  stout,  tapering  throughout,  not  much  longer

Nearly  uniform  dull  luteo-testaceous,  with  the  usual  fuscous  slender 
scalariform  markings  on  the  hind  femora  and  short  longitudinal  fuscous 
dashes  on  the  posterior  portions  of  the  abdominal  segments,  repeated 
vaguely  as  cloudy  markings  on  the  meso-  and  metanotum;  pronotum 
slightly  infuscated  anteriorly  and  posteriorly.  Antennae  moderately 
slender,  the  legs  exceptionally  short.  Fore  femora  distinctly  though 
only  slightly  stouter  than  the  middle  femora,  scarcely  longer  than  the 
pronotum  and  much  less  than  half  as  long  as  the  hind  femora,  the 
inner  carina  unarmed.  Middle  femora  with  a  single  preapical  spine 
on  the  front  carina,  and  on  the  hind  carina  a  single  small  spine  or  none 
besides  a  tolerably  long  genicular  spine.  Hind  femora  somewhat 
shorter  than  the  body,  exceptionally  broad,  about  two  and  a  half  times 
longer  than  broad,  almost  two  and  a  half  times  longer  than  the  fore 
femora,  strongly  arcuate  beneath,  strongly  and  sharply  constricted  be- 
fore the  geniculation,  with  a  very  few  raised  points  on  the  middle  of  the 
inner  side  above,  the  outer  carina  closely  serrulate,  the  inner  carina  dis-

Ceuthophilus  unispinosus  Brunn.,  Monogr.  Stenop.,  64  (1888). 

Luteous,  heavily  irrorate  with  more  or  less  confluent  fuscous  dots, 
giving  it,  as  Thomas  well  expresses  it,  a  mossy  appearance ;  the 
amount  of  confluence  and  accordingly  of  infuscation  varies  somewhat 
in  different  individuals,  and  is  usually  deepest  on  the  pronotum,  which 
also  often  shows  on  either  side  a  larger  or  smaller  rufo-luteous  patch 
free  from  dots  ;  the  hind  femora  retain  the  usual  scalariform  markings, 
which  are  narrower  than  common.  Antennae  moderately  stout  at 
base,  very  slender  beyond,  three  or  four  times  as  long  as  the  body. 
Legs  rather  short.  Fore  femora  scarcely  stouter  than  the  middle 
femora,  about  a  fourth  longer  than  the  pronotum  and  much  less  than 
half  as  long  as  the  hind  femora,  the  inner  carina  with  a  long  subapical 
spine.  Middle  femora  with  a  long  subapical  spine  on  the  front  carina 
sometimes  accompanied  by  1—2  shorter  ones,  the  hind  carina  with  a 
single  subapical  spine  besides  the  genicular  spine.  Hind  femora 
almost  as  long  as  the  body,  considerably  more  than  twice  as  long  as 
the  fore  femora,  very  stout,  apically  tapering  rapidly  especially  in  the 
g ,  the  distal  fifth  subequal,  about  two  and  a  half  times  longer  than 
broad  ( $ ),  the  darker  portions  heavily  scabrous  with  raised  points, 
besides  a  sparse  sprinkling  of  the  same  on  the  apical  half  of  the  inner 
surface,  the  outer  carina  minutely  and  bluntly  bi-  or  tri-serrulate, 
sometimes  with  a  large  preapical  triangular  dentiform  spine  serrulate 
on  its  proximal  edge  (<?)  or  unarmed  (9),  the  inner  carina  similar 
but  in  the  distal  half  more  coarsely  uniserrulate,  the  serration  stopping 
abruptly  before  the  apex  with  a  distinct  denticle,  sometimes  produced 
to  a  stout  triangular  spine,  serrulate  on  the  proximal  edge  (<?)  or  with

a  few  feeble  raised  points  or  spinules  on  the  apical  half  (  9  ),  the  inter- 
vening sulcus  broad  and  V-shaped.  Hind  tibiae  strongly  and  sharply 
bowed  just  before  the  middle,  and  on  the  proximal  portion  prominently 
and  roundly  laminate  beneath,  by  reason  of  the  bow  no  longer  than 
the  femora  (  $ )  or  straight  and  simple,  slightly  longer  than  the  fem- 
ora (  9  ) ,  armed  beneath  with  a  single  preapical  spine  and  an  apical  pair  ; 
spurs  subopposite,  the  basal  pair  but  little  before  the  middle  of  the 
tibia,  about  as  long  as  the  tibial  depth,  set  at  an  angle  of  about  45° 
with  the  tibia  and  divaricating  but  little  more  than  that,  the  tips  feebly 
incurved  ;  inner  middle  calcaria  slightly  longer  than  the  outer,  more 
than  twice  as  long  as  the  others  or  as  the  spurs,  and  as  long  as  the  first 
tarsal  joint.  Hind  tarsi  about  two  fifths  the  length  of  the  tibiae,  the 
first  joint  fully  as  long  as  the  rest  together,  the  second  nearly  three 
times  as  long  as  the  third  and  almost  equal  to  the  fourth.  Cerci  stout 
in  the  basal  half,  beyond  tapering,  not  more  than  half  as  long  as  the 
femoral  breadth,  except  in  the  female.  Ovipositor  gently  tapering  in 
the  basal  half,  slender  beyond  and  finely  pointed,  scarcely  upturned  at 
tip,  about  two  thirds  as  long  as  the  hind  femora,  the  inner  valves

the  several  segments  being  somewhat  uniformly  and  rather  closely 
covered  with  blister-like  elevations,  largest  and  closest  next  the  dorsal 
line.  Neither  Thomas  nor  Brunner  has  noticed  this  peculiarity.

markings  are  reduced  to  a  narrow  mesial  luteous  stripe  ;  the  hind  fem- 
ora are  similarly  speckled  in  place  of  the  usual  markings,  though  these 
sometimes  prevail.  Antennae  very  slender,  probably  about  twice  the

H.  K.  Morrison,  coll.  S.  Henshaw  ;  1  £,49,  Oregon,  and  Placer, 
Kern,  and  Los  Angeles  Counties,  Cal.,  mostly  from  the  Riley  collec- 
tion (U.  S.  Nat.  Mus.). 

The  male  of  this  species  is  remarkable  for  the  surface  sculpture  of 
the  dorsum  of  the  abdomen,  the  first  seven  segments  of  which,  but 
particularly  the  second  to  the  sixth  inclusive,  are  densely  covered  with 
minute  strongly  .elevated  tubercles,  besides  which  on  the  anterior  por- 
tion of  the  first  to  the  fifth  segments  and  almost  crossing  the  segment 
is  a  mesial  series  of  large  slightly  transverse  tumid  elevations,  rounded 
anteriorly,  truncate  posteriorly.  I  have  seen  nothing  resembling  it  in 
any  other  species,  excepting  to  a  less  degree  in  its  next  neighbor, 
C.  pacificus ;  this  and  the  peculiar  characteristics  of  the  outer  hind 
femoral  carina  make  this  a  very  striking  species,  which  I  take  pleasure 
in  dedicating  to  my  colleague,  Mr.  Samuel  Henshaw. 

54.     CEUTHOPHILUS  DEVIUS,  sp.  nov. 

Nearly  uniform  brownish  testaceous,  subglabrous,  with  very  feeble 
infuscated  obscure  blotches  especially  upon  the  pronotum,  and  a  fine 
mediodorsal  luteous  thread  running  the  length  of  the  body ;  surface, 
especially  in  $  and  particularly  on  the  thorax,  very  finely  sub- 
corrugate.  The  antennae  are  coarse  at  base  (beyond  broken),  the 
joints  more  or  less  thickened  apically.  The  legs  are  rather  short. 
Fore  femora  much  less  than  half  the  length  of  the  body,  hardly  a  fifth 
longer  than  the  pronotum,  a  little  stouter  than  the  middle  femora  and 
a  little  less  than  half  as  long  as  the  hind  femora,  the  inner  carina  with 
a  preapical  spine  and  a  few  (9)  or  many  (<J)  spinous  points;  the  fore 
tibiae  with  a  single  median  spine  on  the  inner  side  above,  and  beneath 
with  3  (9)  or  4  (  £)  pairs  of  stout  spines.  Middle  femora  with  5—6 
(9)  or  8-9  ((J)  spines  on  the  fropt  carina,  the  preapical  small,  at  least 
in  the  £,  the  hind  carina  similarly  armed  and  with  a  small  genicular 
spine.  Hind  femora  considerably  shorter  than  the  body,  distinctly 
more  than  twice  the  length  of  the  fore  femora,  nearly  straight  above 
in  the  $  where  they  are  of  nearly  equal  breadth  on  the  proximal  two 
thirds  and  are  then  somewhat  abruptly  emarginate  beneath,  less  than 
three  and  a  half  times  as  long  as  broad  in  both  sexes,  the  surface 
glabrous  with  no  raised  points  excepting  sparsely  scattered  ones  on 
the  upper  surface  in  the  middle  half,  the  outer  carina  of  both  sexes 
with  equal  slight  denticulations  on  the  constricted  portion  of  the 
femora,  the  inner  carina  with  larger  denticulations  throughout  (except 
at  base)  much  larger  and  more  unequal  in  the  <J,  where  the  largest 
are  as  long  as  the  tibial  spurs,  the  inferior  sulcus  narrow.  Hind  tibiae

straight,  of  the  same  length  as  the  femora,  stout,  basally  constricted, 
beneath  with  a  row  of  distant  spines  besides  the  apical  pair  ;  spurs  sub- 
opposite,  the  basal  pair  at  the  end  of  the  proximal  third  of  the  tibia, 
scarcely  longer  than  the  tibial  depth,  set  at  an  angle  of  45°  with  the 
tibia  and  divaricating  70-80°  ;  inner  middle  calcaria  but  little  longer 
than  the  outer,  about  half  as  long  again  as  the  others  or  as  the  spurs, 
shorter  than  the  first  joint  of  the  tarsus.  Hind  tarsi  about  one  third 
as  long  as  the  tibiae,  the  first  joint  scarcely  longer  than  the  fourth  and 
less  than  twice  as  long  as  the  second  and  third  together,  the  sec- 
ond but  little  longer  than  the  third.  Cerci  rather  slender,  tapering 
throughout,  pointed,  much  shorter  than  the  femoral  breadth.  Ovi- 
positor nearly  straight,  scarcely  longer  than  the  fore  femora,  the  basal 
half  tapering,  the  apical  slender  and  equal,  the  tip  pretty  strongly 
upcurved  to  a  fine  point,  the  teeth  and  especially  the  apical  tooth  very 
long,  slender,  and  arcuate.

By  the  brevity  of  the  first  and  second  hind  tarsal  joints  and  the 
slight  enlargement  of  the  fore  tibiae  in  the  male,  this  species  approaches 
the  genus  Phrixocnemis,  but  the  normal  development  of  the  armature 
of  the  hind  tibiae  forbids  placing  it  there. 

55.     CEUTHOPHILUS  NEOMEXICANUS,  sp.  nov. 

Dark  testaceous  or  castaneous,  glabrous,  broadly  but  gradually 
infuscated,  especially  above,  on  the  posterior  margins  of  all  the  seg- 
ments, and  on  the  anterior  portion  of  the  pronotum,  which  is  otherwise 
more  or  less  slightly  mottled,  beneath  and  on  the  lower  portions  of  the 
sides  invariably  lighter  and  generally  more  nearly  unicolorous.  Legs 
testaceous,  the  hind  femora  externally  with  a  feeble  median  longi- 
tudinal infuscation  sometimes  visible  only  on  the  distal  half,  where  it 
is  often  diffused  and  accompanied  by  feeble  slender  herring-bone 
iufuscations  on  either  side,  the  hind  tibial  spines  feebly  infuscated  at 
apex.  The  antennae  are  not  very  slender  and  the  legs  short.  Fore 
femora  distinctly  stouter  than  the  middle  femora,  but  little  longer  than 
the  pronotum  and  less  than  half  as  long  as  the  hind  femora,  the  inner 
carina  with  a  subapical  spine,  sometimes  accompanied  at  variable

distances  by  a  smaller  one.  Middle  femora  with  1—4  spines  on  the  front 
carina,  most  numerous  in  the  9  and  the  subapical  the  largest,  the 
hind  carina  similarly  armed,  but  one  spine  genicular  and  the  others  as 
numerous  in  the  <J  as  in  the  £.  Hind  femora  much  shorter  than  the 
body,  considerably  more  than  twice  as  long  as  the  fore  femora,  stout, 
being  in  the  $  less  than  three  times  as  long  as  broad,  with  hardly  any 
subapical  constriction,  that  is,  tapering  almost  regularly  to  the  apex, 
the  surface  with  no  raised  points,  the  outer  carina  pretty  regularly  and 
rather  minutely  denticulate  in  the  distal  half  or  less,  exclusive  of  the 
geniculation  (<J),  or  minutely  denticulate  throughout  (9),  the  inner 
carina  similar  to  the  outer,  but  in  the  $  more  extensively  denticulate 
than  the  outer,  the  intervening  sulcus  narrow.  Hind  tibiae  straight  in 
both  sexes,  distinctly  shorter  than  the  femora,  the  upper  surface 
rather  broad  in  the  <J  and  basally  constricted,  beneath  with  a  longer 
( $ )  or  shorter  ( 9  )  series  of  median  spines,  besides  the  apical  pair ; 
spurs  subopposite,  the  basal  pair  at  the  end  of  the  proximal  third  of 
the  tibia  (£),*  about  as  long  as  the  tibial  depth  ($),  or  two  to  three 
times  as  long  as  the  tibial  depth  (9),  set  at  an  angle  of  about  50° 
(cJ)  or  30°  (9)  with  the  tibia  and  divaricating  as  much,  their  tips 
scarcely  incurved ;  inner  middle  calcaria  not  greatly  longer  than  the 
outer,  less  than  half  as  long  again  as  the  others  or  as  the  (<£)  spurs, 
nearly  as  long  as  the  first  tarsal  joint.  Hind  tarsi  much  less  than 
two  fifths  as  long  as  the  tibia,  the  first  joint  not  so  long  as  the  rest 
together,  the  second  but  little  longer  than  the  third  and  with  it  a  little 
shorter  than  the  fourth.  Cerci  rather  slender  and  regularly  tapering, 
pointed,  considerably  shorter  (<£)  or  considerably  longer  (9)  than 
the  hind  femoral  breadth.  Ovipositor  about  two  thirds  as  long  as  the 
hind  femora,  its  upper  margin  feebly  arcuate,  the  apical  two  thirds 
subequal,  the  apex  slightly  upturned  and  very  acuminate,  the  teeth  of 
the  inner  valves  long,  aciculate,  the  distal  arcuate.

The  species  is  most  nearly  allied  to  G.  devius,  from  which  it  differs 
principally  in  its  smaller  size  and  the  armature  of  the  femora. 

••The  single  9  I  have  seen  has  four  pairs  of  spurs  on  one  tibia,  the  basal 
pair  at  the  end  of  the  proximal  fourth  of  the  tibia,  while  the  other  tibia  has  but 
a  single  non-opposite  pair  in  the  middle  of  the  tibia.  It  is  further  anomalous  in 
the  excessive  length  of  the  spurs,  in  contrast  to  the  $ .

I  cannot  find  any  species  which  corresponds  sufficiently  with  Halde- 
man's  description  to  apply  this  name  to  it.  When  we  are  better 
acquainted  with  the  forms  occurring  in  the  South,  west  of  the 
Alleghanies,  we  may  be  able  accurately  to  fix  it.  It  was  described 
from  Selma,  Alabama.

resemble  G.  valgus.  It  comes  from  Mt.  Nebo,  Utah.  (See  Appendix.) 

NOTE.  —  Ceuthophilus  cubaensis  Walk.  (Locusta  Rhaphidophora  cubensis  De

to  the  Anostostomata. 

PHRIXOCNEMIS  (<£pt£os,  /cn^t?;),  Gen.  nov. 

Closely  allied  to  Ceuthophilus,  and  having  its  general  aspect,  though 
the  legs  are  stouter  than  is  commonly  the  case  in  that  genus.  Head 
rather  large,  the  vertex  well  rounded  and  deflexed,  barely  interrupted 
from  continuation  into  the  frontal  costa  by  the  confluence  of  the 
antennal  scrobes.  Eyes  small,  subpyriform,  as  large  as  the  antennal 
scrobes.  Antennae  as  in  Ceuthophilus.  Palpi  very  small,  the  ante- 
penultimate joint  but  little  shorter  than  those  on  either  side  of  it. 
Pronotum  sub-semicylindrical,  the  inferior  margin  of  the  descending 
lateral  lobes  arcuate,  the  anterior  and  posterior  angles  equally  or 
almost  equally  rounded ;  those  of  the  meso-  and  metanotum  similarly 
rounded  without  the  posterior  oblique  truncation  common  in  Ceutho- 
philus, or  present  in  the  slightest  degree.  Anterior  coxas  compressed 
and  elevated  to  form  a  median  denticle.  Legs  short  and  rather  stout. 
Fore  femora  stout,  or  at  least  broad  by  compression.  Middle  femora 
unarmed  apically,  or,  when  armed,  only  by  an  inferior  and  brief  spine

on  the  posterior  side,  the  geuicular  lobes  very  small.  Hind  femora 
very  broad  and  incrassate,  even  the  extremity  stout,  both  inferior 
carinae  feebly  denticulate,  rarely  with  any  conspicuous  spines.  Fore 
tibiae  unarmed  above,  enlarged  in  the  male  ;  middle  tibiae  armed  above 
with  several  pairs  of  spines  besides  those  beneath ;  hind  tibiae  stout,  no 
longer  than  hind  femora,  armed  beneath  with  a  single  apical  spine 
besides  the  apical  pair  and  above  with  lateral  spines  of  two  classes : 
a  larger  series  of  generally  long  stout  spines,  longer  than  the  calcaria, 
and,  especially  in  the  9>  becoming  longer  and  more  crowded  apically, 
the  4—6  spines  of  one  row  not  greatly  divergent  from  those  of  the 
other ;  and  minute  denticulations  occupying  the  interspaces,  at  least  on 
the  proximal  half  of  the  tibia  and  the  proximal  free  portion,  but,  at 
least  in  the  9 ,  commonly  absent  from  the  distal  half  of  the  tibia ;  the 
three  pairs  of  apical  calcaria  are  not  widely  different  in  length.  Hind 
tarsi  short,  much  less  than  half  as  long  as  the  tibiaa,  the  first  and  fourth 
joints,  and  the  second  and  third  joints,  respectively  subequal,  the  latter 
together  much  shorter  than  either  of  the  others.  Ovipositor  equal  in 
breadth  throughout,  when  viewed  laterally  scarcely  or  not  taperiug  in 
the  basal  half.

pale  luteous,  becoming  rufo-luteouson  the  dorsum,  where  it  is  heavily 
marked  with  blackish  or  blackish  fuscous,  particularly  on  the  posterior 
margins  of  the  segments,  the  abdominal  segments  almost  wholly 
brownish  fuscous  with  only  an  anterior  luteous  stripe,  the  meso-  and

but  smaller  tooth  upon  the  genicular  lobe  ( <J)  or  with  a  post-median 
spine  much  shorter  than  the  shortest  tibial  spurs,  another  pregenicular 
spine  of  smaller  size,  and  between  them  6-8  spinules  (9),  the  inner

PHRIXOCNEMIS  VALIDUS,  sp.  nov. 

Nearly  uniform  testaceous,  glabrous,  with  feeble  infuscation  in 
clouds  upon  the  sides  of  the  pronotum,  and  to  a  scarcely  perceptible 
degree  upon  the  whole  dorsum,  made  more  evident  by  a  fine  medio-

with  miuute  denticulations,  the  intervening  sulcus  not  broad.  Hind 
tibiae  considerably  shorter  than  the  femora,  straight,  stout,  armed 
beneath  with  a  single  small  preapical  spine,  besides  the  unusually  long 
apical  pair ;  the  four  pairs  of  spurs  are  opposite  or  subopposite,  the 
basal  near  the  end  of  the  proximal  third  of  the  tibia,  regularly  increas- 
ing in  length  distally,  so  that  the  last  are  as  long  as  the  nearest  calcaria, 
while  the  proximal  are  but  little  more  than  half  that  length  or  than 
the  tibial  depth,  set  at  an  angle  of  70-80°  with  the  tibia  and  divaricat- 
ing only  about  20°,  the  whole  feebly  incurved,  the  tips  not  more  so ; 
the  spurs  are  also  more  closely  crowded  on  the  distal  half  of  the  tibia 
than  before  it,  and  indeed  so  crowded  as  to  have  no  intervening  spines, 
which  even  between  the  others  are  few  in  number  and  irregular,  the 
two  distal  spurs  with  the  proximal  calcaria  being  at  uniform  distances 
apart,  a  distance  hardly  one  half  that  which  separates  the  preceding 
spurs ;  all  the  calcaria  are  subequal  in  length,  those  of  opposite  sides 
similar,  but  they  decrease  slightly  from  above  downwards,  and  the 
longest  is  as  long  as  the  first  to  third  tarsal  joints  combined.  Hind 
tarsi  hardly  more  than  a  third  as  long  as  the  tibiae,  the  first  and  fourth 
joints  subequal  and  either  of  them  much  longer  than  the  subequal 
second  and  third  joints  combined.  Cerci  moderately  stout,  equal  and 
single  jointed  in  proximal  half,  tapering  pointed  and  multiarticulate 
beyond,  the  whole  about  as  long  as  the  width  of  the  hind  femora.

Vertex  smooth.  Rather  bright  luteo-testaceous,  subglabrous,  very 
broadly  marked  with  blackish  fuscous  especially  in  a  broad  anterior 
bordering  to  the  pronotum,  and  a  broader  or  narrower  posterior  bor- 
dering to  all  the  segments,  relatively  broader  on  the  abdominal  than 
on  the  thoracic  segments,  but  on  the  latter  sometimes  reinforced  by  a 
stout  mediodorsal  stripe  deeper  in  color  posteriorly  than  anteriorly ; 
the  interior  edges  of  the  anterior  and  posterior  borderings  of  the  pro- 
notum are  very  irregular,  and  particularly  show  subdorsal  posterior 
thrusts  of  the  anterior,  and  laterodorsal  anterior  thrusts  of  the  posterior 
bordering;  the  lower  borders  of  the  thoracic  segments  are  broadly 
luteous  and  immaculate ;  the  legs  are  luteous,  the  femora  infuscated 
more  or  less  especially  beyond  the  middle,  the  hind  pair  with  more  or

This  genus  is  remarkable  for  lacking  the  third  tarsal  joint  of  the 
fore  and  hind  legs.  Brunner  (Monogr.  Stenop.,  60,  foot-note)  pre- 
sumed this  to  be  an  abnormal  condition  found  in  a  single  specimen 
seen  by  me ;  but  it  was  seen  and  specially  remarked  upon  both  by 
Haldeman  and  Girard  before  me,  and  I  have  examined  fourteen  speci- 
mens of  both  sexes,  all  of  which  agree  in  this  particular  except  that 
in  two  or  three  of  them  the  fore  or  hind  tarsi,  or  both,  are  broken, 
so  that  it  cannot  be  affirmed  of  them.  There  can  be  no  question  that 
it  is  normal  as  no  specimen  of  the  two  species  has  been  found  in  which 
the  condition  was  different.

The  specimens  described  by  me  as  a  Ceuthophilus  belong  to  this 
species,  though  separately  described  at  the  same  time. 

Specimens  are  recorded  as  having  been  taken,  or  have  been  seen 
by  me,  from  Perry  Co.,  111.,  Dr.  E.  R.  Boardman  (Uhler) ;  Illi- 
nois (Uhler,  Comstock,  McNeill)  ;  Southern  Illinois  and  Rock 
Island,  111.  (Uhler) ;  Red  River,  Manitoba  (Caulfield)  ;  Carbery,

(Bruner);  Missouri  (Broadhead)  ;  Sedalia,  Mo.  (U.  S.  Nat.  Mus.) ; 
Dakota  (Bruner),  and  Colorado,  5,000'  (Morrison)  ;  so  that  its  general 
range  appears  to  be  between  the  Mississippi  River  or  a  little  east  of 
the  main  stream  to  the  Rocky  Mountains  between  Lat.  37°  and  50° 
North.  But  I  have  two  specimens  in  my  collection,  one  from  North 
Carolina  (Shute),  the  other  from  El  Dorado  Co.,  Calif.,  4,000'  (Giss- 
ler),  both  of  them  far  beyond  the  otherwise  known  limits  of  the 
species.  Of  the  latter  locality  I  entertain  no  doubt,  especially  as  I 
have  recently  found  in  the  Museum  of  Comparative  Zoology  a  single 
specimen  collected  by  Morrison  in  Arizona;  but  as  to  the  former  I  am 
inclined  to  believe  the  label  became  accidentally  attached  to  the  wrong 
insect,  particularly  as  Shute's  collection  was  made  on  the  seaboard.

APPENDIX. 

After  this  paper  was  in  type,  I  received  from  the  Davenport  Academy 
of  Natural  Sciences,  through  the  kind  intervention  of  Prof.  Herbert 
Osborn,  of  Ames,  Iowa,  the  single  type  of  Ceuthophilus  utahensis 
Thorn,  (see  p.  102),  and  append  a  description  of  it  to  render  this  paper 
more  complete.  It  is  not  so  closely  related  to  C.  valgus  as  I  had  sup- 
posed from  the  description  and  figure,  but  belongs  rather  in  the  near 
vicinity  of  G.  uhleri  and  C.  blatchleyi,  though  with  the  inferior  sulcus 
of  the  hind  femora  not  so  exceptionally  broad  as  in  those  species,  and 
also  with  very  different  markings,  in  which  respect  it  recalls  rather 
C.pallidus.  The  measurement  of  the  hind  tibiae  given  by  Thomas 
is  too  great.  The  specimen  was  collected  in  alcohol,  but  has  since 
been  pinned. 

Brownish  fuscous  with  dull  luteous  markings ;  on  the  pronotum  the 
fuscous  borders  all  the  margins  broadly,  the  anterior  and  lateral  mar- 
gins very  broadly,  sending  backward  from  in  front  a  broad  mediodorsal 
stripe  nearly  meeting  the  posterior  bordering,  and  through  it  runs  a 
faint  median  luteous  thread ;  the  posterior  bordering  throws  forward 
on  either  side  a  subdorsal  tooth  embracing  the  posterior  end  of  the 
mediodorsal  stripe  and  leaving  between  the  two  a  U-shaped  luteous 
mark  which  connects  the  luteous  disks  of  either  side,  the  latter  of 
which  are  more  or  less  mottled  with  fuscous  lines  ;  the  me'so-  and 
metanotum  are  heavily  spotted  anteriorly  with  partly  confluent  luteous 
spots,  and  the  abdominal  segments  are  more  regularly  margined  an- 
teriorly with  luteous  ;  legs  warm  luteous,  the  hind  femora  with  the 
usual  scalariform  infuscations.  The  antennae  are  moderately  slender 
and  more  than  twice,  probably  thrice,  as  long  as  the  body,  and  the 
legs  moderately  long.  Fore  femora  no  stouter  than  the  middle  femora, 
a  little  less  than  half  as  long  as  the  hind  femora,  scarcely  more  than  a 
third  longer  than  the  pronotum,  the  inner  carina  with  a  moderately 
long  preapical  spine  preceded  by  a  shorter  one.  Middle  femora  with 
a  single  moderately  long  spine  on  the  front  carina  and  on  the  hind 
carina  1-2  short  spines  besides  a  moderate  genicular  spine.  Hind 
femora  nearly  as  long  as  the  body,  somewhat  more  than  twice  as  long 
as  the  fore  femora,  moderately  stout,  only  the  distal  sixth  subequal, 
about  three  and  a  quarter  times  as  long  as  broad,  the  surface  with  a 
very  few  raised  points  along  the  upper  edge  of  the  inner  side,  the 
outer  carina  considerably  and  subequally  elevated,  with  about  fifteen 
coarse  but  rather  small  subequal  and  inequidistant  spines,  the  longest

not  a  third  as  long  as  the  tibial  spurs,  the  inner  carina  with  a  series  of 
rather  distant  short  spinules  partially  biseriate,  the  intervening  sulcus 
broad,  equal,  and  deep.  Hind  tibiae  rather  feebly  and  broadly  sinuate 
(this  point  is  exaggerated  in  the  original  figure),  a  very  little  longer 
than  the  femora,  armed  beneath  with  a  single  long  preapical  spine 
besides  the  apical  pair  ;  spurs  subalternate,  the  basal  beyond  the  end 
of  the  proximal  third  of  the  tibia,  nearly  twice  as  long  as  the  tibial 
depth,  set  at  an  angle  of  about  35°  with  the  tibia  and  divaricating 
about  80°,  their  apical  third  or  fourth  considerably  incurved ;  inner 
middle  calcaria  considerably  longer  than  the  outer,  fully  twice  as  long 
as  the  others  or  as  the  spurs,  but  somewhat  shorter  than  the  first  tarsal 
joint.  Hind  tarsi  about  two  fifths  as  long  as  the  tibiae,  the  first  joint 
as  long  as  the  rest  together,  the  second  and  fourth  subequal,  and  each 
about  twice  as  long  as  the  third.  Cerci  rather  stout,  tapering  regu- 
larly, about  as  long  as  the  femoral  breadth. 

Length  of  body,  14.5  mm. ;  antennae,  31+  mm. ;  pronotum,  4.4  mm. ; 
fore  femora,  6  mm. ;  hind  femora,  13  mm. ;  hind  tibiae,  13.5  mm.
